Severity: normal

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.

Now you can no longer expect a long running background processes to
continue after logging out. I believe this breaks the expecations of
many users. For example, you can no longer start a screen or tmux
session, log out, and expect to come back to it. For this reason, I
think it is a bad decision on the part of the systemd maintainers to
enable this feature by default, and it should rather be disabled by
default in Debian, either by compiling systemd with
--without-kill-user-processes or by setting KillUserProcesses=no in
/etc/systemd/logind.conf.
