That has been in loader.conf the whole time.

It isn't.  There is another machine right next to it running 9.2-RC1
and it works fine with the mountpoint=/ setting and an empty fstab.

And it worked fine on *this* machine on 9.1.  It's not clear what
changed to stop it from working after upgrading to 9.2-RC3.

If time permits, we will update our PXE install environment to 9.2 and
rebuild the whole thing.  That would eliminate the upgrade step and
hopefully give a result others could reproduce.

Setting mountpoint=/ is necessary in order for "zpool import -o
altroot=/mnt data" to do the right thing at maintenance time.

Thanks!
