> Why do you want to do that? Well, when you have a machine with virtualization you can share the /usr partition across all instances, physically.

Or you could share the whole /usr over NFS to hundreds of diskless workstations, each having their own separate / (also shared over NFS). Remember that disk space was expensive back then; having hundreds of identical copies of the large /usr tree on the NFS server would be a huge waste.
