Subject: latest -current upgrade and CFS

CFS is the crypto filesystem that Matt Blaze did.  Essentially, you
talk to it via NFS and it decrypts/encrypts files on the fly which are
stored elsewhere in the UNIX filesystem.

I just upgraded my system running an older -current to the version
checkout as of last night.  My cfsd stopped working; it appears the
the NFSv3 default is the cause of this problem, and the
"auto-fallback" to NFSv2 mechansim doesn't work with cfs.  I had to
add the '-2' option to the mount command to get things working; I
recompiled cfsd for good measure too.

So my /usr/local/etc/rc.d/cfs.sh now looks like:

if [ -x /usr/local/sbin/cfsd ]; then
	/usr/local/sbin/cfsd && \
		mount -o port=3049,intr,-2 localhost:/null /crypt
fi


Note that this still requires the one-line fix to correctly parse
mount options with parameters, like the 'port=3049', in the file
/usr/src/sbin/mount/getmntopts.c.  I submitted a PR on this on quite a
while ago:

Hope this saves someone some time..
