Uh, Solaris is very purposely System V and the old Sun OS (anything pre 5.6) was very purposely BSD. As in, Sun said that's what they were trying to do. (Never you mind /usr/ucb, silly user. You're not suppoed to know that exists anyway. If we wanted you to know what it was there for, we'd have called in /usr/bsd, and if we wanted you to use it, we'd have made /usr/ucb/ps execute in something resembling a sane period of time.) > Digital Unix, aka Tru64 Unix was the only version of Unix to ever > actually implement the OSF code.

More than OpenBSD, FreeBSD, and NetBSD, arguably. It's 4.2 BSD based because it's NeXTStep-based... and NeXTStep is painfully BSD everywhere it isn't painfully NetInfo. (Go on, ask me why I don't boot my NeXT turbocube much. Okay, I'll tell you: a friend was using it on Swarthmore's campus for a while, and since the disk is small, configured a lot of things, including a lot of non-essential, though oft-used, libraries on the other end of an NFS mount. But I can't, for the life of me, get far enough into NetInfo without the whole thing hanging on an NFS read that will simply never work to switch those mounts OFF.) Then, of course, they hired FreeBSD people to spruce it up. Whatever. > As for "direct member," it depends upon which branch and how much > incest you want to allow for - USG vs OSF and all that good stuff. Now > AIX is more System V than BSD with a measure of OSF thrown in. I just mean "source is based on something that had some real right to be called Unix at some point". And by "based on" I don't mean "behaves like", but "is the product of a function performed on the original code". > Linux is most definitely NOT a Unix(tm)... because Unix(tm) is a brand > name and there is an entire suite of tests which must be passed before > one gets to pay the fee that allows one to call your thing -- Unix(tm). > And you'll never catch Linus trying to pretend it is a Unix or calling > it one. Linus has a very good concept of just what his OS is and isn't (well, um, duh :^>). But there are plenty of people out there who don't. > Some go so far as to claim -- if it doesn't respond to "man hier" it's > not "really" Unix. (hier is the description of the "Standard file > system hierarchy"). I'd agree with that in a second. I don't think it's going particularly far. (Now, if it doesn't have hier(7) because MANPATH is broken or you didn't install the manual, that doesn't count. ;^>) I don't know that having hier(7) means you're Unix-derived, though. > /local is a new invention. Before that it was /usr/local and before > that it didn't exist Not sure how you mean you see /local being used... at cs.swarthmore.edu, /usr/local is locally built software that's NFS shared from the server to the workstations in the lab and /local is the overflow of the (way too big for just the OS) truly local hard disk. I'd had the impression we were following some kind of common practice in doing that (and I maintain that it's a sane interpretation, even if that's not the case ;^>). > And then of course is /usr/opt... :) [Dammed if I know, some vendors > use it some don't.] Or even just /opt, which I don't see in *my* hier(7), but I'm reading a BSD one. ;^> I blame commercial vendors (who are also responsible for today's gross abuses of LD_LIBRARY_PATH). > Next we can go argue Unixness on Computer Science grounds -- is a > micro-kernel or a monolithic-kernel "Unix." Oh, either or. It depends on whether you're running it to think about OS design or running it to get real work done. ;^> > By the way, I counted 723 on the head of my pin... Heh.
