Hi Nicolas!

Interesting. I have elogind installed, too, and I also have that
mountpoint at /sys/fs/cgroup/elogind, but nevertheless, uninstalling
cgroupfs-mount sufficed for me. IIRC I didn't do a reboot since then,
though.

Mine looks very similar, yet not identical:

1:name=elogind:/581
0::/

No idea what the 581 refers to. It's not the process id of
elogind-daemon.

Yay! </sarcasm>

(And thanks for testing!)

Overly broad dependencies on libpam-logind and the like seem to be
rather common these days in Debian. :-(
