It would be nicer though to have it all > integrated in the Shepherd. I'm not sure. The beauty of Shepherd, in my eyes, when compared to other init systems, is that it is lean and clean. Leveraging what's already out there (and part of GNU) seems an obvious path to me, as it: 1. Means less code to write, document and maintain. 2. Creates more cohesion between various components of the GNU project. > (Basically, it=E2=80=99s a choice we could make right away: do we move all > network daemons, plus things like guix-daemon, dbus-daemon, etc. etc. to > inetd services, or do we instead extend the Shepherd to support socket > activation? I=E2=80=99m rather in favor of the latter, but if in Guix Sy= stem we > build an abstraction that can equally well target inetd or a future > Shepherd version, that=E2=80=99s even better.) We could start with just targeting inetd, and build the abstraction later, if the need arises, perhaps? We may never need it. Thanks, Maxim
