The concept really comes from the original unix, which back in the
day, often had really tiny boot disks and might mount everything else
over the network or use different drive types to hold the larger /usr
space.   And it would still be nice to be able to do that from a small
flash disk, etc.   But you are right, I don't think Linux ever did it
correctly anyway....
