Shame on me. I'll fix this in the next version right after we reach a consensus
on all the patches.

We already have some cfg- stuff implemented under server- and client-, not
mentioning that we already have some aliases too, so I think it's a bit late
for this now that we follow the philosophy of placing server-related cfg stuff
under server- and client-related stuff under client-, so I think having
daemon-generic cfg stuff under daemon- might be reasonable.
