Bug#1056066: systemd: rsyslog fails to start if /dev/xconsole exists

[Sven Joachim]

Package: systemd
Version: 255~rc2-1
Severity: important

After upgrading systemd from 254.5-1 and rebooting, rsyslog failed to
start on my system.  These messages appear in the journal:

,----
| Nov 16 16:58:10 localhost systemd[1]: Starting rsyslog.service - System Logging Service...
| Nov 16 16:58:10 localhost (rsyslogd)[674]: Failed to create destination mount point node '/run/systemd/mount-rootfs/dev/xconsole', ignoring: Read-only file system
| Nov 16 16:58:10 localhost (rsyslogd)[674]: Failed to mount /dev/xconsole to /run/systemd/mount-rootfs/dev/xconsole: No such file or directory

| Nov 16 16:58:10 localhost systemd[1]: rsyslog.service: Scheduled restart job, restart counter is at 1.
`----

This gets repeated a few times, and after five restart attempts systemd
gives up.

It should be noted that I have enabled forwarding messages to xconsole
according to the the "Logging to xconsole" section in
/usr/share/doc/rsyslog/README.Debian, and the problem is obviously in
the bind mount for /dev/xconsole.  Removing /dev/xconsole so that the
"BindPaths=-/dev/xconsole" statement in rsyslog.service has no effect
lets rsyslog start, but recreates the problem of #1053913.
