Creates more cohesion between various components of the GNU project. Heheh, Guix was started to address #2 actually. Today, I think #2 is okay but should not be an obstacle. As for #1, sure, but Shepherd will need to grow a proper event loop anyway, so socket activation won=E2=80=99t make much of a difference. Also, taking a step back, systemd undoubtedly changed user expectations for the better in terms of integration, monitoring, and logging. Having the same level of integration in the Shepherd would be a step in that direction. >> (Basically, it=E2=80=99s a choice we could make right away: do we move a= ll >> 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?

We may never need it. Yes, so what I had in mind is, in Guix System, something like , which would kinda look like but be lowered (for now) to an inetd service. Thanks, Ludo=E2=80=99.
