I looked a bit into this, and I think shepherd is doing the right
working as expected, making the socket blocking before executing
guix-daemon (it’s clear when stracing it on Linux).

So there must be something specific at play on the Hurd.

I tried this snippet (server on one side, client on the other side) and
it works as expected: ‘accept’ blocks and subsequent read does not get
EAGAIN.

So I’m at loss here.  Does ‘tests/systemd.sh’ succeed when ran natively?
(In particular the check added in
8d31cafbdcb818160852a5d1e6fc24c1a9c53e41.)

Thanks,
Ludo’.
