Comment 12 for bug 1750013

Thanks Dan.

About cgmanager: if we don't have it installed, it does not affect memory of systemd-logind tool per se. What happens, IMHO, is even more severe: we don't free/de-allocate sysfs cgroup paths for sessions. So, in my tests _without_ cgmanager, after 8000 SSH sessions to my target machine, I found 8000 folders with some files each at /sys/fs/cgroup/systemd/user/<my_user>/ .

Although it doesn't directly affects systemd-logind memory footprint, it certainly affects system memory overall. So, in my consideration (given cgmanager has even code glue added to systemd on Trusty), I'd suggest to make it a dependency, not sure why it isn't anyway - for me, this cgroup folders' leak is clearly a bug.
