The Shepherd is decoupled from Guix. In general, when hacking on it, you should think of it as an independent piece of software, a user of which is Guix. A corollary is that there are well-defined interfaces between the two. Usually, you cannot add a new interface in the Shepherd an expect to use it right away in Guix System. In particular, when running =E2=80=98guix system reconfigure=E2=80=99, you = have to keep in mind that the last step, which injects new services (or service replacements) into the running PID=C2=A01, is potentially talking to an old shepherd that does not implement the latest and greatest interfaces=E2=80=94think of a machine that hasn=E2=80=99t been rebooted in = ages. That said, it=E2=80=99s often useful to test Shepherd changes in Guix Syste= m, of course. To do that, you can modify the =E2=80=98shepherd=E2=80=99 field of so that it points to your local package variant. I=E2=80=99m afraid I=E2=80=99m not really answering your questions, but I h= ope it makes some kind of sense. :-) Thanks, Ludo=E2=80=99.
