Default Re: Two identical machines sharing the /usr directory?

It seems to me that it'd be a lot easier if you just copied and
symlinked big directories in the existing configuration to the NFS
mount.

For example, if /usr/local is packed, and you've mounted an empty
directory from the other machine on /mnt/morespace, do something like
this:

cp -pRv /usr/local/* /mnt/morespace/ulocal
rm -r /usr/local/*
ln -s /mnt/morespace/ulocal /usr/local

This is simply a matter of TCP/IP setup. Configure the spare NIC's
with two addresses on a new network different from the one they're
already on, and connect the NFS mount to that new IP address. It'll
have to go over that NIC, given the destination address.
