I just opened my Red Book and reread «Short history of UNIX». Berkley University bought license for AT&T UNIX[1] in 1977. They started to develop their own software for UNIX and distribute it, so this variant of UNIX is called BSD. Then they decide to remove and rewrite original AT&T code, due to license and associated costs, and released 4.3BSD[2], which then used by BSD flavors. So BSD is UNIX, but it contains no A…

Yes, my point is that since *BSD does not contain the original UNIX code anymore, it is no more UNIX than Linux is, since it was basically rewritten from scratch.

I understands your point but it's wrong because UNIX is system, not a single component. UNIX was generic name until it trademarked. See books, see complete code: http://minnie.tuhs.org/cgi-bin/utree.pl . As you can see, BSD UNIX still contains lot of code from BSD UNIX.

The SUS is irrelevant to this question, just like POSIX, which you mention yourself. Probably not a single version of UNIX from Bell Labs could be called UNIX by these definitions, which is silly. Of course they are UNIX, more so than any other operating system. So what makes an operating system a UNIX? Decide for yourself! UNIX != UNIX®

Of course they could, after all they are the genesis of such certification, at very least the v1.0 of it.

No. There's no way any Bell Labs UNIX could conform to either POSIX or SUS.

Legendary indeed ! I assume the author of this message is not using a pseudonym ?

No idea who you are thinking of, but yes this is a pseudonym based on a 1970s krautrock album.

Doug McIlroy, the author of the message referred to in this thread.

He asked about the Kernel. The Kernel is XNU / Mach, modified to act like a monolithic/hybrid kernel. The BSD code in Mac OS X is all user space, much of which probably isn't in iOS at all.

Nope. Part of kernel as well: https://en.wikipedia.org/wiki/XNU#BSD

What sort of things could/can VMS do that Unix couldn't? I know almost nothing about computer history.

VMS had early support for clustering and associated technologies like shared filesystems with a distributed lock manager. VMS had amazing support for terminal servers, so that each terminal user could choose among several connected computers. Terminal I/O was almost completely offloaded: it was common for other users to get delays and random short freezes, but VMS terminal users had smooth responsive I/O all the time…

I recall that you could press Ctrl-T and it would instantly echo back some useful information about the running process, like CPU time and page faults. That was a nifty feature.

I loved VMS. Everything was so coherent, whereas Unix looked like it was hacked together overnight by a bunch of people who never talked to each other. These days, I like Unix, but back in the 80s, I only tolerated it.

I think something like sandstorm is a good balance between this though. Easy enough to setup and you can use whatever cloud software available for it. The feel of shared-hosting, but the control of self-hosting, all in one easy to use package.

I do like cloudron better here for self-hosting. To each his own.
