A while ago someone suggested a /etc/md.conf and an mdon(1) similar to
swapon(1). The md.conf file would contain a simple table indicating what
manner of md devices needs to be created, including fs type and a flag
indicating if it needs to be newfs'ed (as well as newfs parameters, one
assumes), and the mdon(1) would scan fstab and mount any filesystems on
/dev/md*.
This solution is much more flexible than simple /tmp fs on md devices,
seems more appropriate (and scalable) than poluting rc.conf(5) with a
host of new options, and avoids the mount_mdfs criticism leveled by phk
that md is not an fs (which is true enough).
It doesn't look even much difficult to implement either. I bet the most
annoying part would be writing md.conf(5).
Moreover, this solution seemed, at the time, to please all involved in
the discussion. Only none of them went out and implemented it.
