I recall at Berkeley on the VAX we had a /crp filesystem, and it was for
"crap" we didn't want to delete but wasn't very important. I
didn't
realize it was inspired by Research.
At some point someone decided it would be nicer to rename it /arch as an
"archive".
I still have a /arch on my personal machine, for stuff that's large and
(almost) never changes, so it doesn't need to be backed up daily. It
lives on one of those external backup hard disks, and there are two of
them, so one can be stored offsite.

An early UNIX paper shows the system had four
RK05's (4872 512-byte blocks

to poke ROLLIN to copy the full UNIX partition standalone).
/dev/rk0 - available for user packs.
/dev/rk1 - root
/dev/rk2 - /usr
/dev/rk3 - /crp
I think it was just additional storage of "crap".
