Don’t know about display managers, but I have been using `exec sway`
(previously `exec startx`) to avoid exposing a shell if sway crashes.

I add swaylock to setuid-programs in config.scm, which seems to work OK:

    (setuid-programs
     (cons*
      (setuid-program (program (file-append swaylock "/bin/swaylock")))
      %setuid-programs))
