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.
