GNU dmd

GNU dmd is a "Daemon managing Daemons" (or "Daemons-managing Daemon"?), i.e. a service manager that provides a replacement for the service-managing capabilities of SysV-init (or any other init) with a both powerful and beautiful dependency-based system with a convenient interface. It is intended for use on GNU/Hurd, but it is supposed to work on every POSIX-like system where Guile is available. In particular, it has been tested on GNU/Linux, in the Guix System Distribution.

Downloading dmd

dmd in its early development stages. It can be found on the GNU ftp server for alpha releases: (via HTTP) and (via FTP).


Documentation for dmd is available on-line, as is documentation for most GNU software. You may also find more information about dmd by running info dmd.

Mailing lists

The guix-devel mailing list is used to discuss most aspects of dmd, including development and enhancement requests.

Guix-commits receives notifications of commits to the version control repository.

Announcements about dmd and most other GNU software are made on info-gnu (archive).

Security reports that should not be made immediately public can be sent directly to the maintainer. If there is no response to an urgent issue, you can escalate to the general security mailing list for advice.

Getting involved

Development of dmd, and GNU in general, is a volunteer effort, and you can contribute. For information, please read How to help GNU. If you'd like to get involved, it's a good idea to join the discussion mailing list (see above).

Test releases
Trying the latest test release (when available) is always appreciated. Test releases of dmd can be found at (via HTTP) and (via FTP).

Anonymous checkout: git clone git://

You can also browse the Git repository with your web browser:

Road map

A tentative road map was put up in November 2013. Please join the mailing list for discussion.

dmd is currently being maintained by Ludovic Court├Ęs. Please use the mailing lists for contact.

dmd was initially developed by Wolfgang Jährling, with input from other GNU hackers. It was first released in 2003, making it one of the first init systems departing from the venerable System V approach. Its development was then closely related to the GNU Hurd, although it has always supported GNU/Linux as well.

After a looong period of freeze, it was revived in 2013. It saw its first positively-numbered release in December 2013. It has since been used as the init system (PID 1) of the Guix System Distribution.
