/etc/rc.conf and haven't experienced any problems:
tmpmfs_flags="-S -o async"

Is there a way to accomplish this with an fstab entry?

md /tmp mfs rw,async,-s1024m,-S

no,I don't think so. But surely it would be better to just fixup the
standard mount -t path to not call mount_mfs...


Actually there is a way. I too have not been satisfied with the tmpmfs
features in rc, so for some time now I've simply created a hard link:

cd /sbin && ln -f mdmfs mount_md

and then used an entry like this in /etc/fstab:

md /tmp md rw,async,-Sp1777,-s768M 0 0

This works great for me. A simple patch to mtree could make this hard link
part of the base system. Nothing else is needed.

You should use the 'mfs' file system. This works out of the box:

md /tmp mfs rw,-s256m,-S,-Otime,async,noatime 0 0

Don't know. Don't care.
