For these two, we also need to make these really obvious and difficult
to just pass by. Otherwise sites that depend on e.g. 'bos exec' would be
in for a surprise. Or sites that assume they can just rollback to 1.4
binaries and be fine (which they may not for supergroups).

I'm not sure I see any benefit in using old-style fileservers, but
forcing people to change I guess may be going a bit far. Removing the
DAFS ifdef greatly simplifies a lot of code, though. Would it be
objectionable to remove it for the next dev branch?

+1 on all other points. In addition, remove --enable-unix-sockets, which
is already (confusingly) the default, and remove the associated #ifdefs.
Is there any reason to not use unix sockets for SYNC?

And not really a feature change, but perhaps make --enable-warnings the
default when we have gcc?

Are we / how long are we keeping the inode fileserver backend around?
