Hi Danny and all,

Following reports by Daniel Littlewood, who talked about involuntarily
running a second shepherd instance shadowing the previous one (this time
not in a Guix Home context), I realized shepherd itself could avoid this
entirely.

So shepherd will now refuse to start when it determines that an instance
is already listening on its socket:

Feedback welcome!

Ludo’.
