Thanks for looking at this Ludo.

In systemd the systemd-logind.service looks a little like this:

It looks as though it simply executes the systemd-logind program.

Shouldn't our shepherd service simply execute elogind-program-wrapper?
This may also be right because elogind handles things like the laptop
lid being closed, which should be handled even if no one has logged in
