When did Unix first get partitions?
'Partitions' the mechanism, or partitions the term for the mechanism?
The former appeared about V5:
when an RP03 was added; pre-V7, UNIX filesystems were limited to 2^16
so the 406*10*20 blocks of an RP03 had to be split up into partitions
'sections' or 'pseudo-disks' in the documentation) to make all of it
The latter? No idea...
In the Unix V5 rp(4) man page the term "sections" is used. See page 222 of
In "Setting Up Unix - Sixth Edition" the term "partitions" is used,
although the rp(4) man page still used "sections" in V6 and V7. See
