Dave those are ANSI tape labels. Unix does not use them DEC did
although was inconsistent with the use particularly WRT HDR2 records. Tom
Quarles (of spice 3 fame) wrote probably the best version for Unix to deal
with them. I believe I gave a copy but it will be in BSD 4.1 maybe 4.2
compiler syntax. I'll ask him if he ever updated it. Clem

Weren't V5/6/7/etc distributed as
bootable tapes? Set the switch

Yes. They were. We have V6 and V7 tapes (and a V5 disk image). Likely
earlier versions likely did too. What I'd meant was that 2.8BSD is the
first 2BSD that had a bootable tape.
Ah, my mistake.
I think the loader also read just the first block, so woe betide you if
you used a labelled tape...
If I recall, VOL1, HDR1, etc.
