Tested and seems to work okay on FreeBSD 5.4.

nnpfs/freebsd/Makefile-FreeBSD has a funny reference to
KRB5_INC_DIR in nnpfs/freebsd/Makefile-FreeBSD which needs to be
set in /etc/make.conf for things to compile.  I'm pretty sure you
also need to set SYSDIR in /etc/make.conf to point at your kernel
sources which is probably reasonable.

I tried the mv across volumes a few times with a few largish files
(400 MB) and it seems to work, although a lot of other processes
seem to get stuck in nnpfs_lock on the same machine until the mv is
done, and listing the target directory of the rename hangs in nnpfs
on other machines running 0.41 until the rename finished.  A plain
old cp doesn't do either of those things, so maybe there's a
different way to implement the copy+remove without the bad
side-effects?

I'll toss this onto our releng boxes later today to put some more
stress on things and report anything of interest.
