Package: libsepol1
Version: 2.3-1
Severity: important
Tags: patch
The current version of libselinux1.postint runs "telinit u" to tell init
to re-exec itself. This was added so the system can shutdown cleanly
when sysvinit is the active PID 1.
Under systemd this is not necessary since systemd uses a dedicated
systemd-shutdown [1] tool which replaces init on shutdown. This ensures
all file systems can be unmounted cleanly.
Running "telinit u" midway through a dist-upgrade can have unwanted side
effects as the systemd package might be in an inconsistent state. As
you can see at [2], apt decided to remove libaudit0 (which is a
dependency of systemd in wheezy) and replace it with libaudit1. The new
systemd package is not yet unpacked. Running "telinit u" in such a state
will then lead to kernel panic.
Therefore please consider applying the attached patch in your next
upload.
Cheers,
Michael
