That session manager, logind, is a particular mess.

Here you have a daemon that ties into PAM that tries to second guess the kernel regarding what constitutes a session.

Effectively systemd is becoming something akin to Android. It may be using the Linux kernel, but it is not the GNU/Linux we have grown familiar with over the years.

I don't think the kernel has a session concept that corresponds to the session concept of PAM or systemd. (Yes, PAM also has sessions.)

It has some sort of sessions for processes, but that is just something sharing the same name, not the same concept.

systemd session handling is also particularly joyful to debug.
