That's not a very good thing, as it is much more likely to be wrong.
It would be a good thing to have the /dev/root symlink *IF* a valid root
device exists (defined as a device node appearing which has the same
device number as reported by stat on the root directory), if nothing
else because we have had one available for a very long time and this is
needless breakage.
Obviously, if such a device doesn't exist (btrfs, NFS, tmpfs) then don't.
