I'm pretty sure that swapping in V6 took place to
a major/minor number
configured at kernel build time.
Yup, in c.c, along with the block/character device switches (which converted
major device numbers to routines).
You could create a dev node for the swap device, but
it wasn't used for
the actual swapping.
Yes.
We actually dedicated a full 1024 block RF11 fixed
head to the system in
the early days
Speaking of fixed-head disks, one of the Bell systems used (IIRC) an RS04
fixed-head disk for the root. DEC apparently only used that disk for swapping
in their OS's... So the DEC diagnsotics felt free to scribble on the disk.
So, Field Circus comes in to work on the machine... Ooops!
