Oh, I should have explained better here.
Re-spawn works, it's the (daemon) service that might misbehave/go unresponsive without crashing,
i.e. HTTP backend stops responding to API requests but the server is still up.
The job performs a "health-check" and restarts it if it doesn't get the appropriate response.
A concrete situation where this could be of use is for logs.guix that occasionally stops
recording.

Thanks!
I'm still curious as to exactly what/which lines cause shepherd to output the lines.
Cheers,
Bruno
