initramfs-tools: split networking code into separate function
ltsp in ubuntu started using NBD+unionfs+squashfs instead of NFS, and
debian-live uses has a network boot methods using cifs in addition to a
different way of using NFS (i think it also uses unionfs and maybe
squashfs, not just a plain NFS/cifs mount)...
so splitting out the networking related code into a separate function
would move towards not having forked code for all of these different
network boot methods. at least, that's my hope.
