Description Lennart Poettering 2010-07-09 02:33:45 UTC

When booting a system with systemd /cgroup contains the cgroup hierarchies, and they cannot be unmounted on shutdown (or at least /cgroup/systemd cannot, and hence neither /cgroup). Currently, the halt script tries really hard to unmount the FS in a loop, which ultimately fails, but takes quite some time until it gives up.

/etc/rc.d/init.d/halt shoulds simply ignore all directories starting with /cgroup the same way as /proc and /sys are spared.

Comment 2 Lennart Poettering 2010-08-10 13:02:20 UTC

BTW: as it turns out this mount point of the cgroup fs has been mnoved in the kernel, to a place inside of /sys.

Comment 3 Bill Nottingham 2010-08-10 14:05:25 UTC

/sys/cgroup/...? Or somewhere else?

Comment 4 Michal Schmidt 2010-08-25 21:42:19 UTC

Reopening. With systemd-8 it now tries to umount /sys/fs/cgroup/systemd and /sys/fs/cgroup on shutdown.
