According to the Bugzilla case it links to (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=825394):

> It is now indeed the case that any background processes that were still running are killed automatically when the user logs out of a session, whether it was a desktop session, a VT session, or when you SSHed into a machine.

And the reddit comments include a link to a tmux issue where the suggested solution is for tmux to add systemd as a dependency (https://github.com/tmux/tmux/issues/428). Includes some back-and-forth about how all sorts of software would have to change in similar ways to accommodate systemd, instead of systemd just playing nicely with decades of established practice.

I had no idea about that. Does seem a bizarre choice for systemd to do that.

I admin a whole bunch of headless servers and so am often SSHing to them and running long running jobs. Some of them run VNC sessions, and I certainly wouldn't want a VNC session to kill of other SSH sessions by the same user. At least with VNC, I almost never "logout" - they're often autostarted (by systemd) and just get killed when the machine gets rebooted.
