[TUHS] 211BSD Version in the Unix Archive

[TUHS] 211BSD Version in the Unix Archive

Hi All,

I'm currently doing some work with 211BSD and the best version that I've 
come across for my investigations is the one put together by Andre 
Luvisi, based on the distro in the Unix Archive at 
https://tuhs.v6shell.org/UnixArchiveMirror/Distributions/UCB/2.11BSD

So far as I can figure out (and I'm a little bit fuzzy around the 
edges), this appears to be patch level 431, at least according to 
https://tuhs.v6shell.org/UnixArchiveMirror/Distributions/UCB/2.11BSD/VERSION. 
I have a number of questions that hopefully, someone can shed some light on:

1. Is it really pl 431?
2. How can I tell?
3. Is it the latest tape image available (I've seen plenty of disk 
images, but those are already installed)?
4. Is there a howto bring it up to the next patch level document lying 
around somewhere?

I've seen Warner's work on going the other direction and that's 
fascinating in it's own right, but I'd like to see about patching up to 
latest.

Thanks,

Will

You should look at the canonical tuhs archive at
https://www.tuhs.org/Archive/Distributions/UCB/2.11BSD/

VERSION is always updated, so it is. If you are in doubt, you can look at
the patch files that's at
https://www.tuhs.org/Archive/Distributions/UCB/2.11BSD/Patches/ and they
all update VERSION.

Yes. Well, almost.
https://www.tuhs.org/Archive/Distributions/UCB/2.11BSD_patch457/ has a tape
that's updated to 457, lacking only the last 12 changes. A most current
tape hasn't been regenerated, at least in the archives. A quick search of
github shows there's a few PiDP-11 oriented versions but I've not looked
closely at them.

There's two or three efforts to create shell scripts to apply the patches.
I've not looked closely at them all yet...

When my work is done, there will be a github repo that has all the changes
applied, one at a time which can be used to generate context diffs or
something else that can be pushed to the PDP-11s that can be updated.

I'll do that.

Excellent. Thanks for the confirmation.

Got it.

When folks 'regenerate' the tape, is it simply a matter of writing to 
the tape device from the patched disk inside the 211BSD instance or are 
there some arcane activities involved?

Nice. You said something like this the other day, but at the time, I 
didn't quite get how relevant it would be. Now that I understand what 
you're talking about, it sounds great.

Well, I figured out number 4, duh!

4. Is there a howto bring it up to the next patch level document lying
around somewhere?

Each patch is self documenting :). Just do what it says and it should 
work... we'll see!
