installed before we daemonise, otherwise another job might send
USR1 to mountall before the handler is installed, killing it.

as they become available (as determined by monitoring udev) and
emits Upstart events to inform other jobs that the filesystems are
mounted. This is very useful for NixOS (which currently ignores
filesystems in the job dependency chain - very bad).
Unfortunately, mountall depends on Plymouth (a boot splash
implementation). The patch allows mountall to build without
Plymouth. Since Plymouth is also used to inform users about failing
mounts and get responses, some more changes will be needed.
Probably mountall should emit a "mount-failed" event to trigger a
root shell on the console to allow the user to repair the problem.
