sw — POSIX Software Packaging
Software Packaging Layout Software Definitions Software Selections Extended Definitions Distributor Keywords Package Security Software Definition Files: INFO, INDEX, PSF Example Package
A package may exist in two forms: as a directory in a file system, or a serial access tar or cpio archive file. A package consists of two main sections: 1) the exported catalog structure, and, 2) the software file storage structure. Each section may contain path name components which serve to segregate distribution, product and fileset objects.
Shown below is an example with one (1) product and one (1) fileset.
<path>/ <path>/catalog/ <path>/catalog/INDEX <path>/catalog/<dfiles> <path>/catalog/<dfiles>/... <path>/catalog/<prod_dir>/ <path>/catalog/<prod_dir>/<pfiles>/INFO <path>/catalog/<prod_dir>/<pfiles>/... <path>/catalog/<prod_dir>/<fileset_dir>/ <path>/catalog/<prod_dir>/<fileset_dir>/INFO <path>/catalog/<prod_dir>/<fileset_dir>/... <path>/catalog/<prod_dir>/<fileset_dir>/<script> <path>/<prod_dir>/ <path>/<prod_dir>/<fileset_dir>/ <path>/<prod_dir>/<fileset_dir>/<distribution_files> <path>/<prod_dir>/<fileset_dir>/<distribution_files>/...
The exported catalog structure consists of the files with pathnames that begin <path>/catalog. Note that catalog is not a legal prod_dir name. Also, "dfiles", and "pfiles" should not be used as control directory names, they are the default names for the Distribution and Product files directories. The dfiles and pfiles defaults are commonly accepted.
The order of files in a serial access archive is specified and shown above. The order of products and filesets within a product is not specified, although they must be grouped together. Notably, the INDEX file is the first regular file in the package, followed by the <dfiles> directory. For each product, the <prod_dir> is followed immediately by the <prod_dir>/<pfiles> directory.
To support extant usage of tar archives, this implementation supports a minimal package layout. The layout is non-intrusive to the current practice of extracting a 'binary' package in the '/' directory where <path>/ is nil and, likewise to 'source' packages where <path> is typically the package name and version. The use of nil control directories is not attested to in the POSIX standard.
<path>/ <path>/catalog/ <path>/catalog/INDEX <path>/catalog/dfiles/ <path>/catalog/dfiles/INFO <path>/catalog/dfiles/... <path>/catalog/pfiles/INFO <path>/catalog/pfiles/... <path>/catalog/INFO <path>/<distribution_files>/...
In this layout a single product and fileset have control_directory attributes specified as an empty string.
<dfiles> is the value of the dfiles attribute and the default value is "dfiles". This directory can store an INDEX file or INFO file pertaining to the distribution. It can also store an attribute of the distribution as a separate file where file name is the name of the attribute and the file contents the value.
<pfiles> is the value of the pfiles attribute and the default value is "pfiles". This directory can store an INFO file pertaining to the product control_files, control scripts defined in the INFO file, and all other distributor-defined control_files. It can also store an attribute of the product as a separate file.
This directory contains information in the same form as does the Product Files although pertaining to the fileset.
The <prod_dir>/<fileset_dir> names are the values of the control_directory attribute for the product and fileset respectively. The default value is the value of the tag attribute. <prod_dir> must be unique within a distribution and <fileset_dir> must be unique within a product.
The listing of control directories in the exported catalog structure is repeated and files of the distribution appear under these directories in a location determined by the metadata.
The standard does not require that files that are not regular files appear in the storage section.
The Software Definitions are metadata representations of the objects and attributes recognized by the standard. The right hand column in each definition shows the default attribute value. The defining standard for each attribute is indicated as a comment (leading '#' sign) if it is not IEEE-1387.2, other defining standards are XDSA C701 (C701), and, this implementation (impl.).
host hostname hostname None os_name os_name None os_release os_release None os_version os_version None machine_type machine_type None
The host definition was attested to only in the informative annex of the standard. An implementation may chose to define this class.
A host object can contain a distribution, or installed_software object.
distribution layout_version layout_version 1.0 path path Implementation Defined dfiles dfiles dfiles pfiles pfiles pfiles uuid uuid Empty string
The path attribute is not in a PSF nor INDEX files. A PSF does not contain a uuid attribute. An INDEX file will contain a layout_version attribute as the first attribute.
A distribution object can contain bundles, products, and, media in the form of software definitions.
The following attributes are recognized as valuable by the Informative Annex of POSIX.7.2.
tag tag Empty string title title Empty string description description Empty string revision revision Empty string media_type media_type Empty string copyright copyright Empty string create_time create_time Empty string number number Empty string architecture architecture Empty string
The following attributes are recognized by this implementation.
signature < pathname None # impl. sig_header < pathname None # impl. sha1sum < pathname None # impl. sha512sum < pathname None # impl. md5sum < pathname None # impl. adjunct_md5sum < pathname None # impl. files < pathname None # impl. control_directory control_directory Empty string # impl. owner name root # impl. group name root # impl. mode mode 0755 # impl. signer_pgm utility_name GPG # impl. signer_pgm_version version 1 # impl. tar_format_emulation_options program_options # impl. tar_format_emulation_utility software spec # impl.
The url attribute is the universal record locator of the packager qualified vendor. The control_directory attribute in the distribution object appears as the <path> leading directory path in the a serial archive package. The owner, group, and mode attributes control the file attributes of the single path name prefix. The signature, sig_header, md5sum, and adjunct_md5sum attributes are described below and are stored as separate files in the dfiles directory. The tar_format_emulation_* options define the GNU tar version and format options that the archive file mimics, these attributes are used by the 'checkdigest' script.
installed_software layout_version layout_version 1.0 path path Implementation Defined dfiles dfiles dfiles pfiles pfiles dfiles catalog catalog Undefined install_time install_time Undefined # impl.
A software object can be listed (written to stdout) in the form of an INDEX file by the swlist utility.
media sequence_number sequence_number 1
An INDEX file must contain the sequence_number attribute if the distribution spans multiple media.
vendor the_term_vendor_is_misleading true True or False #impl tag tag Empty string title title Empty string description description Empty string qualifier qualifier Empty string # impl. url url Empty string # impl. vendor_tag tag Empty string # impl.
The tag attribute is required. The the_term_vendor_is_misleading is required in a PSF file to avert a (harmless) warning, please use it. It exists to allow persons, for example, who are distributors (of existing free software) to qualify themselves away from the connotations of a "vendor" which has specific meaning not applicable to a free software distributor. A INDEX and PSF files can contain vendor definitions. The vendor_tag attribute contains the vendor.tag of the upstream distributor. The qualifier attribute value may be one of: seller, author, packager, maintainer. A distribution may have more than one vendor definition. They may form a chain of references from the product.vendor_tag to the last vendor referred to by the vendor.vendor_tag attributes.
bundle tag tag architecture architecture Empty string location location <bundle.directory> qualifier qualifier Empty string revision revision Empty string vendor_tag vendor_tag Empty string create_time create_time None description description Empty string contents contents Empty string copyright copyright Empty string directory directory Empty string instance_id instance_id 1 is_locatable is_locatable true layout_version layoyt_version 1.0 machine_type machine_type Empty string mod_time mod_time Empty string number number Empty string os_name os_name Empty string os_release os_release Empty string os_version os_version Empty string size size Empty string title title Empty string category_tag category_tag Empty list or patch # C701 is_patch is_patch false # C701
The tag and contents attributes are required in INDEX and PSF files. The size attribute is not allowed in either file. The value of size is generated dynamically. An INDEX file will contain a instance_id attribute. Bundle definitions for distributions will not contain either the location or qualifier, installed_software objects may contain these attributes.
product tag tag None architecture architecture Empty string location location <product.directory> qualifier qualifier Empty string revision revision Empty string vendor_tag vendor_tag Empty string all_filesets all_filesets Empty list control_directory control_directory <product.tag> copyright copyright Empty string create_time create_time None directory directory / description description Empty string instance_id instance_id 1 is_locatable is_locatable true postkernel postkernel Implemen. defined layout_version layout_version 1.0 machine_type machine_type Empty string number number Empty string os_name os_name Empty string os_release os_release Empty string os_version os_version Empty string mod_time mod_time None size size None title title title category_tag category_tag Empty list # C701 is_patch is_patch false # C701 copyrighters copyrighters None # impl. build_root build_root None # impl. build_host build_host None # impl. source_package source_package None # impl. source_rpm source_rpm None # impl. all_patches all_patches None # impl. url url None # impl. rpm_provides rpm_provides None # impl. change_log change_log None # impl.
The tag and control_directory attributes are required. The size attribute is not allowed in either file. The value of size is generated dynamically. An INDEX file will contain a instance_id attribute. A product object can contain control_files, files, and, subproducts in the form of software definitions.
The product.vendor_tag refers to the downstream distributor. This value is be the analogous to the RPMTAG_RELEASE or debian_release attributes. The original upstream author's package, for example, would not use this attribute because that package would not have a release part in its name, but could (or should) provide a vendor object in the PSF.
The architecture attribute contains an implementation defined name describing the architecture. This attribute may be a pattern. The swbis implementation uses the output of GNU config.guess (timestamp=2007-01-15) as the string to be matched by this pattern.
category tag tag None # C701 title title Empty string # C701 description description Empty string # C701 revision revision Empty string # C701
The Category definition describes attributes of products and bundles related to its category. If is_patch is "true" then category.tag must equal "patch".
subproduct tag tag None create_time create_time None description description Empty string mod_time mod_time None size size None title title Empty string contents contents Empty list category_tag category_tag Empty list # C701 is_patch is_patch false # C701
The tag and contents attributes are required.
fileset tag tag None create_time create_time None mod_time mod_time None control_directory control_directory <fileset.tag> corequisites corequisites Empty list description description Empty string exrequisites exrequisites Empty list is_kernel is_kernel false is_locatable is_locatable true is_reboot is_reboot false location location <product.directory> media_sequence_number media_sequence_number 1 prerequisites prerequisites Empty list revision revision None size size None state state None title title Empty string is_sparse is_sparse "false" # C701 is_patch is_patch "false" # C701 category_tag category_tag empty list # C701 ancestor ancestor <product.tag>,ver_id # C701 applied_patches applied_patches empty list # C701 patch_state patch_state applied or, # C701 committed or, superseded, (no default). saved_files_directory saved_files_directory None # C701 supersedes supersedes None # C701 superseded_by superseded_by None # C701
The tag and control_directory attributes are required. A PSF should not contain the location, media_sequence_number, size, or state attributes. A fileset object can contain control_files, files, in the form of software definitions.
file path path None cksum cksum None compressed_cksum compressed_cksum None compressed_size compressed_size None compression_state compression_state uncompressed compression_type compression_type Empty string revision revision Empty string size size None source source None gid gid Undefined group group Empty string is_volatile is_volatile false link_source link_source None major major None minor minor None mode mode None mtime mtime None owner owner Empty string type type f uid uid undefined archive_path archive_path empty string # C701 md5sum md5sum empty string # impl. sha1sum sha1sum empty string # impl. sha512sum sha512sum empty string # impl. rdev rdev empty string # impl. rpm_fileflags rpm_fileflags empty string # impl.
A PSF must contain source attribute. A source attribute in an INFO will be ignored. A PSF should not contain the cksum, compressed_cksum, compressed_size, compression_state, compression_type, or size attributes.
control_file tag tag None cksum cksum None compressed_cksum compressed_cksum None compressed_size compressed_size None compression_state compression_state uncompressed compression_type compression_type Empty string revision revision Empty string size size None source source None path path None interpreter interpreter sh result result none
A control_file defines a control script such as those listed below (see Extended Control File Definitions) or an attribute stored as a file.
The Software Selections provide a means to specify and select (possibly with a shell matching pattern) specific Software objects. A selection is made using a software spec. A software spec may not contain white space (a list of multiple selections is white space delimited). A software spec consists of tag values and version_ids. Multiple tags are '.' (dot) delimited with the leftmost specifying the broadest (most general) software object such as a bundle or product and the rightmost being most specific (The swbis implementation does not support fileset tags in a software spec). The tags may be followed by nothing, or a comma and one or more Version Identifiers which are ',' comma delimited.
Dependency Specs are software specs.
Version Identifiers specify specific attributes of a software object. There are five (5) specified. They are signified by a single letter: r,a,v,l,q. An implementation may support additional ones and may support qualification to a specific object type by prefixing a 'p' or 'b' or 'f' for bundle, product, or fileset respectively. The value of the attribute follows an equals sign '=', or in the case of a revision id, a relational operator.
Letter Attribute r revision r\<relop\>revsion # A relop may be ==,\<,\>,\<=,\>= v vendor_tag v=vendor_tag q qualifier q=qualifier l location l=location a architecture a=arch
Implementation Extension Version Ids are the following:
Letter Attribute i catalog_instance_id i=number
The catalog instance_id is a directory in the installed software catalog that distinguishes installed instances of packages with the same name and revision but at different locations.
emacs,r==21.2 kde.kdegames # This assumes that 'kde' was specified as the bundle # in the kdegames package foobar,r\>1.0,v=tycoon003 somepackage,r\>1.0,r\<=1.3 # revision is the product revision by default somepackage,pr\>1.0,pr\<=1.3 # explicitly specify revision is the product revision
A dependency spec is a software spec. There are three types: prerequisites, exrequisites, corequisites. These attributes apply to the fileset and are placed in the fileset object in a PSF file. A prerequisites is something that must be installed, and a exrequisites is something that must not be installed. A corequisites is something that must be installed with, corequisites are not supported at this time. prerequisites map to RPMTAG_REQUIRENAME, RPMTAG_REQUIREVERSION, and RPMTAG_REQUIREFLAGS attributes.
# Alternation Require a package named foo1 or foo2 prerequisite foo1|foo2 # Require a package named foo1 and foo2 prerequisite foo1 foo2 # multiple prerequisite keywords can be used prerequisite foo1 prerequisite foo2 # Require a revision range and a certain vendor_tag prerequisite foo1,r>2,r<3,v=mydist*
A Product Specification File (PSF) can contain Extended Definitions in the fileset, product or bundle software definitions. They would have the same level or containment relationship as a file or control_file definition in the same contaning object.
Extended Definitions represent a minimal, expressive form for specifying files and file attributes. Their use in a PSF is optional in that an equivalent PSF can be constructed without using them, however, their use is encouraged for the sake of brevity and orthogonality.
The swbis implementation requires that no [ordinary] attributes appear after Extended Definitions in the containing object, and, requires that Extended Definitions appear before logically contained objects. That is, the parser uses the next object keyword to syntacticly and logically terminate the current object even if the current object has logically contained objects.
checkinstall source [path] preinstall source [path] postinstall source [path] verify source [path] fix source [path] checkremove source [path] preremove source [path] postremove source [path] configure source [path] unconfigure source [path] request source [path] unpreinstall source [path] unpostinstall source [path] space source [path] control_file source [path]
The source attribute defines the location in distributors's development system where the swpackage utility will find the script. The keyword is the value of the tag attribute and tells the utilities when to execute the script. The path attribute is optional and specifies the file name in the packages distribution relative to the control_directory for software containing the script. If not given the tag value is used as the filename.
directory source [destination]
Applies the source attribute as the directory under which the subsequently listed files are located. If destination is defined it will be used as a prefix to the path (implied) file definition. source is typically a temporary or build location and dest is its unrealized absolute pathname destination.
Specifies every file in current source directory. The directory extended definition must be used before the recursive specification.
file [-t type] [-m mode] [-o owner[,uid]] [-g group[,gid]] [-n] [-v] source [path]
source defines the pathname of the file to be used as the source of file data and/or attributes. If it is a relative path, then swpackage searches for this file relative to the the source argument of the directory keyword, if set. If directory keyword is not set then the search is relative to the current working directory of the swpackage utility's invocation.
All attributes for the destination file are taken from the source file, unless a file_permissions keyword is active, or the -m, -o, or -g options are also included in the file specification.
path defines the destination path where the file will be created or installed. If it is a relative path, then the destination path of the of the directory keyword must be active and will be used as the path prefix. If path is not specified then source is used as the value of path and directory mapping applied (if active).
type may one of 'd' (directory), or 'h' (hard link), or 's' (symbolic link).
-t d Create a directory. If path is not specified source is used as the path attribute.
-t h Create a hard link. path and source are specified. source is used as the value of the link_source attribute, and path is the value of the path attribute.
-t s Create a symbolic link. path and source are specified. source is used as the value of the link_source attribute, and path is the value of the path attribute.
mode defines the octal mode for the file.
file_permissions [-m mode] [-u umask] [-o [owner[,]][uid]] [-g [group[,]][gid]]
Applies to subsequently listed file definitions in a fileset. These attributes will apply where the file attributes were not specified explicitly in a file definition. Subsequent file_permissions definitions simply replace previous definitions (resetting all the options).
To reset the file_permission state (i.e. turn it off) use one of the following: file_permissions "" or the preferred way is file_permissions -u 000
Excludes a previously included file or an entire directory.
The contents of filename may be more definitions for files. The syntax of the included file is PSF syntax.
A software definition file (INFO, INDEX or psf) may contain keywords not recognized by the standard. Such keywords will be parsed as an attribute keyword, that is as an attribute of the containing object (keyword) software definition.
The Package Security Attributes are distribution attributes stored as separate files. They are implementation extensions. They consist of archive digests, catalog signature, catalog signature header, and individual file md5, sha1, and sha512 digests.
md5sum, sha1sum, and sha512sum are the md5 and sha1 and sha512 digests (ascii representations) of the leading package directories that do not have the catalog pathname component followed by the software file storage structure portion of the uncompressed serial access package file including all archive format trailer blocks.
<path>/catalog/<dfiles>/md5sum <path>/catalog/<dfiles>/sha1sum <path>/catalog/<dfiles>/sha512sum
adjunct_md5sum is the same as the md5sum excluding symbolic links. If a package does not contain symbolic links the md5sum and adjunct_md5sum will be identical.
Explanation: This attribute is called 'adjunct' because it is a digest of a subset of the files in the package. It exists to facilitate verifying file integrity of the directory form of a package in an environment where the modification time of symbolic link files are not preserved from the serial archive by the tar utility or operating system. The ability to verify even the adjunct_md5sum from the directory form of the package is dependent on the tar creating utility and other attributes of a POSIX.2 environment.
The sig_header file is a ustar header that is identical bit-for-bit to the ustar header of the signature file. It always precedes the signature file archive members.
The sig_header protects the tar header of the signature files from tampering. This is required because neither the signature file bytes nor the signature tar header are included in the signed data.
The signature protects the metadata section of the archive. The contents of payload section are only included in the form of a crytographic digest. The sha1 digest is preferred over the md5 digest for technical reasons. If the metadata section does not contain the payload section digests then there is no way to verify the payload from the signature.
The signed data is the exported catalog structure of the uncompressed serial archive package file up to but not including the first byte of the software file storage structure followed by two (2) 512 byte null blocks if tar format, and no trailer bytes if not tar format. The signature file archive member itself is not included in the signed stream, it is intended that the <path>/catalog/<dfiles>/md5sum file is included in the signed stream.
The signature file is ASCII armored. The last printable character of the signature is followed by one or more newline characters (0x0A). The total length of the file must match the file size specified in the size field of the sig_header file. The ustar header of every signature archive member shall be identical to the sig_header file. The padded size is predetermined [by swpackage] and currently set to be 1024 octets. This means the armored sig file has a length limitation of 1023 octets.
If multiple signature archive members exist they must follow one another in the archive with no other intervening files; and, the same sig_header file is the ustar header for all the signature archive members. A signature archive member, whether alone or one of many, is never part of the signed data stream.
file.cksum file.md5sum file.sha1sum file.sha512sum
Each file can have none or all of these digests.
The metadata files, INDEX, INFO and PSF, contain information about the software in the form of software definitions. The INDEX and INFO files appear in a package directory structure. They are automatically generated by the 'swpackage' command. The location in the directory structure indicates the higher level object to which their data pertains. The PSF file does not appear in the package. It is created by a person or program and it directs the action of the swpackage utility. It is internal data unless released by the distributor.
The files contain keywords (and values) to represent the attributes defined in the standard. There are three (3) different keyword types: object, attribute, and, extended. The object keyword type has no value and there are eleven (11) of these corresponding to the Software Definitions defined above: installed_software, distribution, media, bundle, vendor, category, product, subproduct, fileset, control_file, file.
Each object keyword is followed by and newline and attributes in the form of keyword/value pairs. Whitespace separates the keyword and value. Whitespace outside of a quoted value is not significant. A quoted value can span multiple lines. An object keyword with its list of attribute keywords (and values) forms a Software Definition. A Software Definition is terminated by the start of the next Software Definition. Extended keywords (meaning Extended Definitions) only appear in a PSF file.
The order of objects (i.e Software Definitions) is significant and a containment hierarchy is determined according to parser's grammar.
A '#' (pound) character designates a comment. A comment may begin a line or appear at the end of a single line containing the keyword/value pair.
A value may be quoted by the '"' (double quote) character; and, multi-line values must be quoted. Trailing white space from an unquoted value will be removed.
The order of attributes is not significant although the INDEX file grammar requires the layout_version attribute appear first in distribution or installed software object.
The ", #, and, \ characters must be escaped with a backslash (\\) in a quoted value.
If a value begins with a < (less than), the value is interpreted as a filename whose contents will be treated as a quoted value although the storage of the attribute will be in the form of a control file (i.e. a separate file in the control directory). For INDEX files, the filename is relative to the control directory in which this attribute is contained. For PSF files, the filename is a path on the host.
A PSF may contain all Software Definitions. An INDEX file does not contain control_file, or file definitions. An INFO file contains only control_file, and file definitions.

This section describes attribute usage and conventions imposed by the swbis implementation. Not all attributes are listed here. Those that are have important effects or particular interest.
The standard defines a limited set of attributes for the distribution object. An expanded set is suggested by the informative annex however a conforming implementation is not required act on them. The reason for this is a distribution may be acted upon by a conforming utility in such a way that attributes of the distribution become invalid. For this reason, some attributes that refer to an entire "package" [in other package managers] are referred from the product object and attain their broadened scope by the distributor's convention that their distribution contains just one product.
For example, the package NAME and VERSION are referred from the product tag and revision, not the distribution's. This convention supports multiple products in a distribution and is consistent with the standard.
tag is the short, file system friendly, name of the distribution. Providing a distribution tag is optional. The swbis implementation will use this as the [single] path name prefix if there is no distribution.control_directory attribute. A distribution tag attribute and swpackage's response to it is an implementation extension. The leading package path can also be controlled with the ”-W dir” option.
control_directory, in a distribution object, is the constant leading package path. Providing this attribute is optional. A distribution control_directory attribute and swpackage's response to it is an implementation extension. The leading package path can also be controlled with the ”-W dir” option. This attribute will be generated by swpackage if not set in a PSF.
A bundle defines a collection of products whether or not the distribution has all the products present.
tag is the short, file system friendly, name of the bundle. This value is used by the swbis implementation as a path name component in the installed software catalog. If it is not present the product tag is used.
A product defines the software product.
tag is the short, file system friendly, name of the product. This value is used by the swbis implementation as a path name component in the installed software catalog. It is required. The swbis implementation uses it in a way that is analogous to the RPMTAG_NAME attribute, namely as the public recognizable name of the package.
Is the directory name in the distribution under which the product contents are located. This value has no affect on the installed software catalog. If it is not given in a PSF then the tag is used.
Is the product revision. It should not contain a "RELEASE" attribute part or other version suffix modifiers. This value is used by the swbis implementation as a path name component in the installed software catalog. It is required by swinstall.
This is a short identifying name of the distributor that supplied the product and may associate (refer to) a vendor object from the INDEX file that has a matching tag attribute. This attribute is optional. This attribute value should strive to be unique among all distributors. The swbis implementation modifies the intended usage slightly as a string that strives to be globally unique for a given product.tag and product.revision. In this capacity it serves to distinguish products with the same revision and tag from the same or different distributor. It most closely maps to the RPMTAG_RELEASE or "debian_revision" attributes. It is one of the version distinguishing attributes of a product specified by the standard. It is transfered into the installed_software catalog (not as a path name component) by swinstall. If this attribute exists there should also be a vendor object in the PSF in the distribution object that has this tag. This attribute is assigned the value of RPMTAG_RELEASE by swpackage when translating an RPM.
This string is one of the version attributes. It is used to disambiguate products that have the same tag, revision and vendor_tag. It is not used for determining a products compatibility with a host. The form is implementation defined. swbis uses the output of GNU config.guess as the value of this string. A wildcard pattern should not be used. The canonical swbis architecture string can be listed with swlist. For exampleswlist -a architecture @ localhost
Here are some example outputs from real systems.System `uname -srm` architecture Red Hat 8.0: Linux 2.4.18 i686 i686-pc-linux-gnu OpenSolaris: SunOS 5.11 i86pc i386-pc-solaris2.11 NetBSD 3.1: NetBSD 3.1 i386 i386-unknown-netbsdelf3.1 Red Hat 4.1: Linux 2.0.36 i586 i586-pc-linux-gnulibc1 Debian 3.1: Linux 2.6.8-2-386 i686 i686-pc-linux-gnu
os_name os_release os_version machine_type
These attributes are used to determine compatibility with a host. They correspond to the uname attributes defined by POSIX.1. If an value is nil or non-existent it is assumed to match the host. All attributes must match for there to be compatibility. Distributors may wish to make these values a shell pattern in their PSF's so to match the intended collection of hosts. swbis uses fnmatch (with FLAGS=0) to determine a match.
A fileset defines the fileset.
tag is the short, file system friendly, name of the fileset. It is required although selection of filesets is not yet supported therefore the end user will have little to do with the fileset tag.
Is the directory name in the product under which the fileset contents are located. This value has no affect on the installed software catalog. If it is not given in a PSF then the tag is used.
This PSF packages every file is current directory. It uses nil control directories so the package structure does not change relative to a vanilla tarball.

This is a sample PSF for a runtime package. It implies multiple products (e.g. sub-packages) using the bundle.contents attribute. Since the bundle and product tags exist in a un-regulated namespace and are seen by end users they should be carefully chosen. Note that the bundle and product have the same tag which may force downstream users to disambiguate using software selection syntax such as fooit,bv=* or fooit,pv=* .
