Are you installing GuixSD 0.10.0?

I would personally find it weird to warn about the possibility of losing
Internet connection.  This is outside the scope of GuixSD, in a way.

WDYT?

However, in the past people reported that nscd, the name service cache
daemon, would sometimes fail without any good reason.  If you think that
is the case, then this is definitely a bug that we should be
addressing.

Thanks,
Ludo’.
