Good.

Weird.  (I’ve installed GuixSD/GNOME/NM on a laptop that’s almost always
on a wired network and it doesn’t have this problem AFAIK.)

Could you enable nscd debugging output, so we can at least see whether
the problem is due to nscd caching name lookup failures?  Something
like:

       (modify-services %desktop-services
         (nscd-service-type config
                            => (nscd-configuration
                                (inherit config)
                                (debug-level 3)
                                (log-file "/var/log/nscd.log"))))

Nice.  The attached patch adds this dependency, changing the closure
size from 356 MiB to 360, which I think is reasonable:

OK to apply?

Thanks,
