scripts for review

[Rick Macklem]

Hi,

Hope you don't mind, but I committed the 3 one line changes without
review, since I am away next week and wanted them in for code slush.

I left the larger change to mountcritremote out, since it could be
riskier at this time (although it seems to work ok for me).

There is the nfsd change that I think allows nfsserver to be deleted.

I'll leave that one at
   http://people.freebsd.org/~rmacklem/rc.conf
for review when someone has the time to do it.
