This is what Jared said in the original message...

        I came up with this simple patch to getfsspecname that allows 
ROOT=<part> 
        syntax for fs_spec. It uses the value of the kern.root_device sysctl to 
        construct a device path, so my fstab can have entries like this:

           ROOT=a          /               ffs     rw,noatime      1 1
           ROOT=b          none            swap    sw      0 0
           ROOT=e          /boot           msdos   rw      1 1

which is exactly what I have been saying is useful.   The "ROOT=" gets replaced
by /dev/$(sysctl -n kern.root_device) which will produce (effectively)

        /dev/sd2a       /       ffs ...
        /dev/sd2b       none    swap...
        /dev/sd2e       /boot   msdos ...

assyming the root has been found on sd2

If you thought that Jared, or I, were suggesting anything different, you 
misread somewhere.
