Yup, in c.c, along with the block/character device switches (which converted
major device numbers to routines).

Yes.

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!
