Bug#803013: systemd should not destroy application created cgroups

[Paul Szabo]

Dear Martin,

Where would I set that? My cgrulesengd (from package cgroup-tools) is
started from /etc/init.d/cgred, not from some systemd *.service thing.
My cgrulesengd sets things under
   /sys/fs/cgroup/cpu,cpuacct/
and I do not see that mentioned in any systemd config-type files.

You mean file
 
debian/patches/debian/cgroup-don-t-trim-cgroup-trees-created-by-someone-el.patch
within
   systemd_232-25.debian.tar.xz
or already in say
   systemd_215-17+deb8u2.debian.tar.xz
No, it is not (and was never) sufficient: that is a different bug.

Thanks, Paul
