Specifies whether the processes of a user should be killed
when the user logs out. If true, the scope unit corresponding
to the session and all processes inside that scope will be
terminated. If false, the scope is "abandoned"
(see {manpage}`systemd.scope(5)`),
and processes are not killed.
See {manpage}`logind.conf(5)` for more details.
Defaulted to false in nixpkgs because many tools that rely on
persistent user processeslike `tmux`, `screen`, `mosh`, `VNC`,
`nohup`, and more would break by the systemd-default behavior.
