This I disagree with. Networking should bring the network up. If
something is necessary to bring the network up, it should be available
locally. Remote filesystems should come _after_ the network is up.
If a program needed to bring networking up is on a remote fs, then there
is a problem with the system project. If it so happens to work without a
fully functional network, good for it, but it's designer must shoulder
the burden of supporting it. The standard way of doing things should be
get the network up, and _then_ mounting the remote fs.
Daemons which _depend_ on network are not part of networking, of course.
