Theo De Raadt added the changes a few days ago to support quotas in mfs. I
finished testing it out today (the last piece was getting quotaon to deal
with the mfs:???? mount table convention and Theo added that fix for me to

What I do is keep disk copies of the quota db files and have rc copy these
over to the mfs before quotacheck.  Then I have a script copy the db files
to disk whenever I run edquota.  I have it print out what it's doing too,
so if the script ever gets hosed,  I will "miss" the verbose output.

Just thought I'd let you guys know in case anybody else is interested in
doing the same.
