Bug#802780: systemd: systemctl 227 fails in chroots (instead of ignoring)

[Stephan Suerken]

Package: systemd
Version: 227-2
Severity: normal

Dear Maintainers,

with 227-2 (not found in 226-2), systemctl behaves differently
in chroots for (at least) services that only provide a sysv init
script, breaking package install or removal:

226-2, jessie: Ignored, retval 0:
 # root? systemctl restart non-existing.service
 Running in chroot, ignoring request.
 # root? systemctl restart wicd.service
 Running in chroot, ignoring request.

227-2, sid: Fails, retval 6:
 # root? systemctl restart non-existing.service
 Failed to restart non-existing.service: Unit non-existing.service failed to load: No such file or directory.
 # root? systemctl restart non-existing.service
 Failed to restart non-existing.service: Unit non-existing.service failed to load: No such file or directory.

As systemctl is also run implicitely via invoke.rc.d on postinst
etc., this actually breaks package installation/removal on such
systems (one current example is the wicd package).

Fwiw, calling systemctl as /sbin/runlevel still works fine:

# root? /sbin/runlevel
Running in chroot, ignoring request.

Hth!
