What is /etc/rmtab? On my slink computer, it is a mile long...

I thought /etc/mtab was used here, not /etc/rmtab.

However, I think if nfsd thinks there are open files, then there
really are open files. You can't just unmount / on a Unix system, even
on shutdown. Normally, it is remounted readonly.

I don't think swap via NFS is a good idea. swap space needs to be
fast.
