[edit] OSF/1 codebase?

What was the codebase used for OSF/1? Was it SVR3, BSD, some mixture? The article says:

After the OSF gave up on OSF/1, DEC renamed OSF/1 AXP to Digital UNIX and made it the main operating system for the company's Alpha processors. It was 64-bit and retained the basis on the Mach kernel but with components from Berkeley Software Distribution, System V, and other sources.

Were these BSD and SysV components already present in OSF/1, were they imported directly or from Ultrix? Qwertyus 18:24, 13 April 2006 (UTC)

The code base for OSF/1 was 4.3-Reno from Berkeley, Mach 2.5 from MIT, and System V Release 2 via IBM from AT&T. There was no Ultrix code in the original code base. 98.197.222.98 11:26, 22 August 2007 (UTC)

[edit] Hybrid kernel?

Another question: could the OSF/1 kernel rightly be called a hybrid kernel? Qwertyus 16:01, 18 April 2006 (UTC)

It's debated whether Mach is actually a Microkernel to begin with, so this is not necessarily a meaningful question. :) -- 98.197.222.98 11:40, 22 August 2007 (UTC)

[edit] POSIX compatibility holes?

I'd love to see references to the POSIX compatibility holes. From what I've seen, Tru64 is usually more compatible than older commercial *NIX's! —The preceding unsigned comment was added by 209.63.53.142 (talk • contribs) .
