Right, libpam_systemd is responsible for both starting a logind session for it as well as setting up the per-user runtime dir and env variables like the above. > 2.

On both my Debian sid and my Ubuntu system, the only difference between common-session and common-session-noninteractive is that the latter does not include libpam-systemd. Thus on a system which does *not* use any additional pam module, this should effectively be a no-op change and thus quite safe. Indeed installing libpam-mount only adds itself to common-session, not to common-session-noninteractive. So with this change we would get the desired effect. login, ssh, lightdm etc. all include common-session, so this should be fine.
