The services systemd-random-seed-save.service and
systemd-update-utmp-shutdown.service from systemd 203 don't work,
because they have a RequiresMountFor dependency on /var/lib and
/var/log. Such a dependency produces a cycle, causing systemd to drop
those services:
Fixing conflicting jobs by deleting job poweroff.target/stop
Deleting job systemd-poweroff.service/stop as dependency of job poweroff.target/stop
Deleting job umount.target/stop as dependency of job systemd-poweroff.service/stop
Deleting job -.mount/start as dependency of job umount.target/stop
Deleting job systemd-random-seed-save.service/start as dependency of job -.mount/start
Deleting job systemd-update-utmp-shutdown.service/start as dependency of job -.mount/start
Dropping the RequiresMountFor doesn't work either, because then
/var/... may have meen unmounted or remounted read-only.
Upstream systemd fixes this by doing the actual work from an ExecStop
action in an already-running service than conflicts with
shutdown.target. So I backported that here. The main consequence is
that wtmp shutdown records now get written properly.
The main lesson: shutdown.target is useless for pulling in services
during shutdown if they need to write anywhere.
I tried jailbreaking, but this didn't work as llvm-general is an
optional (but enabled by default) dependency.
Manual patching revealed idris gets confused over the
llvm-general/llvm-general-pure split.
Only affects "useNixUdev = false" and we now include the udev paths for
the latest Debian Wheezy release, so we can properly deploy Hetzner
machines with NixOps again as they've updated their rescue system to
Wheezy.
This fixesNixOS/nixops#137, thanks to @lovek323 for reporting.

The previous version (5.0.26) has been removed from the debian ftp.
As the source URL is now down, our own hydra (not hydra.nixos.org) failed
to build the package.
This problem will occur again in the future since I only updated the URL
without relying on a "more stable" alternative (this merits a specific
discussion).
