It gives "/.."!  This isn't as clean as it could have been (at least on
the MACH system here).  If I've gotten this correctly, /../.. is the
"real" superroot, with bin, lib, etc, dev, and all the boot
paraphernalia.  /../../RFS (aka /..) is the RFS "mount" point for other
hosts, as in "/../host".  /../../RFS/.LOCALROOT is "/".  /bin, /lib, /dev
and /etc are all patched into /../.. using hard links, which can really
be confusing:
	% cd /../..
	% pwd
	/../..
	% cd bin
	% pwd
	/bin
And people complained about slinks.
