[systemd-devel] [ANNOUNCE] systemd v12

[Lennart Poettering]

Heya,

http://www.freedesktop.org/software/systemd/systemd-12.tar.bz2

Quite a number of new features. I'll probably do another blog story
about all of this one of the next days. Here's the exciting stuff, and
below the detailed stuff:

- Bash completion support for systemctl
- Handling of cryttab, fsck, quota, and shutdown in pure C, a normal
  desktop system should be able to boot without a single shell now.
- Automatically kill remaining user sessions when going down.
- Ubuntu support. Yay, welcome to the club!
- We got rid of --session and replaced it with --user.
- A working infrastructure to query system-level passphrases (LUKS, SSL,
  ...) via UI agents, plymouth, console, wall.
- condition logic, which allows us to skip services based on existance
  of file, kernel command line option, or whether a directory is
  empty. If they are skipped they are still useful for synchronization
  purposes.
- "generator" logic. A really minimal facility to allow others projects to
  generate unit files dynamically and integrate them in the systemd
  dependency tree. The crypttab support is implemented as a generator,
  which allows us to support cryptodisks without polluting the code of
  systemd itself with handling this. Other thinkable generators could be
  stuff that generates an automatic .service file for each lxc or kvm
  machine configured.
- support for initrd-less booting but with selinux
- 'systemctl kill' for sending signals to all processes of a service
- tmpfiles now integrates automatic cleanup op directories it manages, a
  la tmpwatch

The cryptsetup logic currently does everything the Fedora logic used to
do, plus a couple of features Debian had on top of that. However, Debian
has a couple of more, and while I think they are more on the crazy side
of things I am not opposed to adding support for those too, and would be
wiling to merge a patch.
