Bug#826260: libpam-cgfs: Breaks systemd user sessions

[Laurent Bigonville]

Package: libpam-cgfs
Version: 2.0.1-1
Severity: critical
Justification: breaks unrelated software

Hi,

The default configuration of libpam-cgfs breaks systemd user session
management.

All the processes started by systemd --user are not properly put in the
correct systemd cgroup. This can be verified with "loginctl user-status"
command.

This is at least breaking stuffs like policykit.

Removing "name=systemd" from the call to the pam module seems to fix
this. I don't think it's the role of libpam-cgfs to mangle with systemd
cgroups.

Regards,

Laurent Bigonville
