Bug#402511: Device nodes are not removed when devices are brought

severity 402511 normal
Further analysis in http://bugs.debian.org/406697 has shown that the
reason the /dev/dm-* devices are not removed, is the fact that udevd has
already been killed by the time the crypto and lvm scripts are run on
shutdown and thus the events created by the kernel are no longer
processed as they would be if the system was running normally.
This reduces the severity of this issue, although IMO the warning messages
currently printed as originally reported should still be avoided.
It remains to be seen what the best solution is for this:
- making sure udev remains running / is restarted, or
- modifying cryptsetup/libdevmapper to remove the /dev/dm-* devices, or
- modifying vgchange to not print the warnings.
It is also still somewhat strange that on shutdown the /dev/mapper/*
devices _are_ removed for crypto devices, but _not_ for lvm.
