I've assembled some notes from old manuals and other sources on the formats used for on-disk file systems through the Seventh Edition: http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html Additional notes, comments on style, and whatnot are welcome. (It may be sensible to send anything in the last two categories directly to me, rather than to the whole list.)

RE: [TUHS] Sprite

by Aharon Robbins

I think you're confused. The DECstation was made by DEC, but used a MIPS processor, not a VAX. SIMH won't be able to do anything with it, although there are likely other MIPS simulators out there to be found.

Re: [TUHS] Sprite

by Cornelius Keck

Jose, TNX for parking Sprite on ftp.es.embnet.org! I just ran into a little problem.. looks as if the node is either down, or not reachable (at least from here (== Plano, Texas): $ ping ftp.es.embnet.org PING bakalao.cnb.uam.es (150.244.80.6): 56 data bytes ^C --- bakalao.cnb.uam.es ping statistics --- 9 packets transmitted, 0 packets received, 100% packet loss $ ftp ftp.es.embnet.org [2 minutes later] ^C$ > generated an ISO from the raw CD and am copying now the CD > contents to disk, which are being made available as > > ftp://ftp.es.embnet.org/pub/misc/TUHS/sprite > and > ftp://ftp.es.embnet.org/pub/misc/TUHS/sprite.iso > > as the copying is done. Beware, it is ~530MB. This goes for both my machine at home, and here at work. Now, www.es.embnet.org responds fairly fast, so I don't think that it's the wire across the big pond. Any ideas? TNX!

Sprite

by José R. Valverde

Would it make sense to add Sprite to the Unix Archives? To me, yes, it was enough UNIX like although it wasn't ATT or BSD derived and it had many advanced features. I had the (small) pleasure to run it on a small number of DECstations back in 1994-1995 out of the freshly published WalnuCreek CD and I still long for some of it features. The distribution is still available at http://www.cs.berkeley.edu/projects/sprite/ j -- These opinions are mine and only mine. Hey man, I saw them first! José R.

But I guess I'm a little biased because I like p4 better > than bk. Both biased and incorrect. There are over 10,000 branches of the linux kernel floating around in BitKeeper (we know, we counted them) and we handle file movement much more nicely than perforce does (we have our own concept of an inode, a pathname is a attribute of an inode just like contents are an attribute of the inode - so you can move A to B, I modify A, you pull from me and the changes apply to B in your tree.) You can be as biased as you want, I don't want to turn this into a SCM discussion, but try and be accurate. About the only thing that p4 does that we don't do is centralized locking; we don't need to do that in a distributed/replicated system but people sometimes want it. -- --- Larry McVoy lm at bitmover.com http://www.bitkeeper.com

Grokline: Tracing the history of Unix IP

by Chris Palmer

Maybe everyone here already knows about this, but I haven't seen anything, so I'm posting it. http://www.groklaw.net/article.php?story=20040524130757328 "We hope with this Grokline project to be able to identify any conceivable legal issues that those wishing to block, slow, hobble or tax GNU/Linux may try to use in future legal assaults on the community. If there are litigation risks, even just from nuisance lawsuits, particularly with respect to patents, we want to find those risks, hopefully before they do, and mitigate or resolve them now. I am personally convinced, as you no doubt are too, that the next wave of attacks on GNU/Linux and the GPL will involve patents." -- http://chris.nodewarrior.org/
