Another reason why the home directory part of /usr was made into
/home is because after doing so, it was possible to mount /usr
read-only, and supply it from a server. This was the so-called
"dataless" method. I wrote a short email message summarizing
what we were doing with this in UC Berkeley Comp. Sci., and mentioning
a paper I had written describing how to create a "dataless"
environment for DEC's OSF1 operating system (see
http://beowulf.org/pipermail/beowulf/2008-July/022210.html)
Not to be pedantic but the OSF/1 “dataless” trick is from 1993 in Jon Forrest’s writeup:

As one of the three people figuring out what DEC had told us was impossible I’m pretty
sure we were the first - our DEC 3000/400s with OSF/1 T1.0 did not have enough disk space
so we struggled to get our network operational serving /usr and /home from the “big” DEC
3000/600 which had two disks (one of which was /home).
