[TUHS] Code bloat

After I had pasted a bunch of 386BSD pl0.24 + a CVS export of 0.8 I did get a booting system.  Then I found an old ftp site that had 0.8  I made a mirror of it, then it disappeared.

So I mirrored it here:

http://vpsland.superglobalmegacorp.com/ install/NetBSD/NetBSD-0.8/Original/NetBSD-0.8/

Although I had some idiot saying that hosting nethack was a virus had I was then blacklisted for a while so if you try to browse or download you’ll have to input a username password.. It’s on the 404 page.

I did some minor work on installing it on Bochs years ago, and VMware, from what I recall, NetBSD 1.0/1.1 can boot 386BSD’s kernel, while the 386BSD boot diskette didn’t work under emulation, NetBSD’s does, and I used that to kickstart an installation.  Same with the boot blocks on the harddisk image.

The 386BSD porting started on 4.3BSD-Reno with patches being fed back
to BSD. Stuff was being thrown out of BSD at the same time for the Net
releases. Must have been difficult. First release was Net/2 + missing
bits and pieces. ftp://ftp.funet.fi/pub/unix/4.3bsd/i386-jolitz/diffs/
Note that Jolitz was never sued for using Net/2 ;)

NetBSD and FreeBSD started as 386bsd 0.1 + patchkits. To "unencumber"
NetBSD the 0.8 release was scrubbed from the net and a pile of files
in cvs were replaced with the text "revision x.y intentionally removed"
and rewritten or taken from a cleaner BSD release.

FreeBSD claiming to be 4.4BSD-Lite based is, I think, a legal fiction.
I could be wrong, but it is far more likely they did it the same way
as NetBSD after the FreeBSD release. I don't believe they
restarted with a clean 4.4BSD-Lite tape, but the FreeBSD handbook
claims that is what they did for the 2.0 release.
