- Dump won't work either. If I remember correctly, the first two blocks
- (on V6) were boot blocks for two different tape drives, followed by
- some stand-alone programs, and (perhaps in the next file) an IMAGE of
- a V6 file system. Then there were mixtures of disk images and tp tape
- files. V7 I'm not sure about; but as tar started (slightly buggy) in
- V7, I vaguely recall that the distribution tapes were n o t in tar
- format, either. I may not be right about that last.
-
- Note, BTW, that the V6 file system is not mountable on a V7 or later
- system, including all current Berkeley and USG releases.

-
- My statement stands. Berkeley is n o t the best reference for proper
- modularisation. Find needs to know about a heckuva nawful lot, but it
- would perhaps be desirable to have more general-purpose tools.

- I believe, Doctor McCoy, that that is what I just said. Yes, cpio
- hit the streets first, in PWB System 1.0, and in all of its descen-
- dants, yeah down unto System III and System V Release 3.0 Version
- 1.1. Those first few releases had no tar. (I know, what held them
- together then?)
-
- And it's UNIXI, not UNII. (Finally, something about standards, eh?)

- Please amend prior letter.
-
- It is neither UNIXI nor UNII, but Unices.
-
- Thank you. ;-)
