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: https://git.savannah.gnu.org/cgit/shepherd.git/commit/?id=787d5a33aea061b5052faa0863c96be722440ce3 Feedback welcome! Ludo’.
