You'll need to run "loginctl enable-linger" first, if you have not already
done so.

Then "systemd-run --scope --user <command> <args>" to override the systemd
default of KillUserProcesses=yes.

Try invoking screen using "systemd-run --user --scope screen".

Systemd made a change a few years ago to kill child processes on logout by
default, with a config option to disable this behavior.

I guess CCIT just figured that one out...
