GNU Emacs mostly does work, however there are a few issues.

• dired on a directory hangs. (Use C-g C-g to break the unresponsive operation.)

• Configuration in src/s/: gnu.h uses bsd-common.h. gnu-kfreebsd.h uses gnu-linux.h -- we probably should too.

  • gnu-linux.h makes a few things depend on /proc (also see HAVE_PROCFS) -- either resort to our own ways, or enhance our procfs accordingly.

    • sysdep.c

• Got a hang when compiling GNU Emacs 23, when it was compiling .el to .elc files. Looked like busy-looping inside glibc. This was not reproducible so far.

• Debian emacs23_23.1+1-2, grubber, (probably) busy-looping in ext2fs on /media/data when resuming emacs23 build in ~/tmp/emacs/emacs23-*/ (dpkg-buildpackage -B -uc -nc 2>&1 | tee L). No modifications to emacs23-* so far, I think. Hangs always in the same place, it seems, and reproducible. Tarred to emacs23-23.1+1.tar.bz2 (beware: empty and zero-permission files: emacs23-23.1+1/.pc/debian-site-init-el.diff/lisp/site-init.el, emacs23-23.1+1/.pc/autofiles.diff/src/config.in~). At hang-time: the rootfs is fine (syncfs -c -s / works; syncfs involving /media/data hangs). Plan: GDB on that ext2fs, and see what's hanging / locked.
