Re: mdmfs /tmp and fstab on 5.0

 Hi folks,

 I usually mount /tmp on the swap via the following fstab entry:

 /dev/da0s1b /tmp mfs rw,nosuid,nodev,nosymfollow 0 0

 only this doesn't work anymore on freebsd 5.0 since mount_mfs doesn't
 exist (seems to have been replaced by mdmfs).
 What's the proper way to accomplish the same thing on 5.0?
 I'd prefer a solution with fstab, so that /tmp gets mounted as early
 as possible.

ln -s mdmfs /sbin/mount_mfs

As I recall, mdmfs wasn't called mount_mfs at the time because the
author wasn't prepared to fight the battle he assumed (probably
correctly) would arise out of doing so.

Yes, that's a workaround I had in mind.

I can't see any problem there, if the mdmfs program is compatible
with mount_mfs.  I mean, the manpage even explicitly says, the mdmfs
utility is designed to be a work-alike and look-alike of the
deprecated mount_mfs(8).  Why then the different name, especially
with the result that it can no longer be used with fstab?  I mean,
the old mount_mfs doesn't seem to exist anymore so there would be no
naming conflict.

Ok, mdmfs is not fully compatible with mount_mfs, since you don't
specify a swap device as parameter but, for example, /dev/md0.
Other than that it seems to work ok, when called as mount_mfs via
fstab (thru a symlink).  I now have the following line in fstab:

/dev/md0 /tmp mfs rw,nosuid,nodev,nosymfollow,-s256m 0 0

Is there any reason that softupdates is enabled on the md filesystem
by default?  Wouldn't async do the trick aswell?

Semantics. It doesn't mount an mfs filesystem, so it shouldn't be called
mount_mfs. I personally think it's a fairly large breach of POLA - this
isn't really an argument I subscribe to either.
