Yes, I did. How else would the other machines work fine.

At least 64 MB, but up to 256 MB depending on usage/purpose of machine.
The main reason I wanted to add swap was because when the machines aren't
in heavy use they run MPI programs. As most people know at heavy usage
they almost always need swap!

Don't focus on the swap as it isn't the issue. My problem is that FBSD
won't mount root over NFS if a local hard drive is present. All I want to
know is how to bypass the check!
