What the fuck is that? What the hell does it mean? I googled a bit but after reading few meaningless discussion like A: "What does it mean? Is it serious? How do I get rid of this". B: "It is for your own good. Suffer and be silent." I got finally an impression that it is harmless and it simple means that systemd mothefucker somehow help to log-in and log-out users and it does something(?) with processes that get started by cron.
Then I came across some RHEL/Fedora bug report where even Lennart Poettering posted his "Won'tfix! It's for your own good. Resistance is futile, keep you mouth shut and suffer with systemd." Somebody called him an idiot in response. :-)
Anyway, the problem occurred only on Debian systems that have been upgraded from Wheezy to Jessie, but not on freshly installed Jessies. So I compared configuration and the difference that... well, it made the difference, was:
session optional pam_systemd.so
line in /etc/pam.d/common-session . I just commented it out and the shitload of annoying log messages stopped.
