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.
