Hi Danny,

I don't have time to do a proper review, but just one comment:

How is that better than:

    (test-assert "file system monitor running"
      (marionette-eval
       '(begin
         (use-modules (gnu services herd))
         (start-service 'monitor-file-system))
       marionette))

'start-service' should return #f if the service fails to start.

Cheers,
Clément
