Thanks for the further information, Bernhard. I'm going to re-assign this bug report to cgroup-bin.

Right, I don't think umounting /sys/fs/cgroup is a sensible behaviour, if the init cgroup-bin init script didn't mount it itself, thus breaking systemd. The cgroup-bin should behave more sensible if systemd is active. If the init script needs to test for that, it can use test -d /run/systemd/system, see http://www.freedesktop.org/software/systemd/man/sd_booted.html > By purging just cgroup-bin I got expected booting again. > > cgroup-bin[455]: Kernel lacks cgroups or memory controller not available, not > starting cgroups. ...
