It certainly wasn't in the code I worked from, which was CVSUPed on Feb 25th or so. It probably needs someone to post an update to the PR or to email the responsible person to remind him that it hasn't been committed yet. So I just did.

The patch I provided defaulted to NOT formatting the
filesystem when used with the -F option. This is the
opposite of the normal behavior, creating the risk of
a /etc/fstab that assumes that the filesystem will not
be formatted being used with a new release that will format
it by default, thus destroying the filesystem. That
would be very very bad.
So here is a new patch that modifies mdmfs / mount_mfs
to behave as it does now, except that it will not format
the filesystem before mounting if you supply the -A
(mount "as-is") option. Thus, to use /etc/fstab to mount
a file-backed filesystem without reformatting the filesystem,
put something like this in /etc/fstab
/dev/md3 /mnt mfs rw,-A,-F /home/bob/mdfile,noauto 0 0
So, here is a patch to add this to the original mdmfs,
as well as a patch to the man page.

It appears that it always formats a new filesystem because that's what
mount_mfs did, and mdmfs is a replacement for mount_mfs. I agree
with you that that should not be the default behavior for a file-backed
(vnode) disk, so I wrote a little patch to fix that:

So, what IS the correct way to create and use file-based file
systems?
Apply the patch above, then something in /etc/fstab like the following will
not reformat the filesystem:
/dev/md3 /mnt mfs rw,-F/vnodes/fileimage,noauto 0 0
If you want it to reformat the filesystem as the old mount_mfs did
(or at least, as the old man pages say it did), then use something like
/dev/md3 /mnt mfs rw,-F/vnodes/fileimage,-u,noauto 0 0
Note that -u MUST follow -F on the command line to have any effect.
This breaks compatibility with the old mount_newfs. I guess I should
have used to opposite sense for "-u". Which still would have broken
compatibility, but not as much. This means that if this patch ever
makes it into a FreeBSD distribution, it is likely to default to formatting
rather than not formatting. This will lead to a nasty surprise if you
aren't expecting it. In other words, don't use this patch unless you
are desperately seeking a solution to a problem that makes it worth
the risk. Don't blame me when some future change in behavior
deletes your important filesystem.
And, can I put quotas on them?
Don't know, but probably.
If applying a patch is a mystery to you, try (assuming you have the
full source installed) something that approximates this:
# cd /usr/src/sbin/mdmfs
# patch < /path/to/patch.file
# make
# make install
If you want to be thorough, apply the following patch to fix the
man page as well:

Is it possible to use quotas on file-backed md filesystems on 5.3? I was guessing that a line in fstab like: md /home mfs rw,-F/vnodes/home,nosuid,nodev,noexec,userquota 2 0 would work but it's not.
