No, that was MULTICS. UNIX V6 and earlier always only had 1 privilege flag (superuser/general user) due to hardware I/D protection limitations on early model PDPs (pre-11), and we're still stuck with it decades later. The CTSS (later DEC's) PL/1 compiler also still sucks, lo these many years later -- I blame much of Unix on that fact. Now, MULTICS -- *that* had granular privileges; record level access control in some cases. I have an emulated Honeywell 680 system with a bootable Multics cloned from dockmaster.af.mil's boot packs (one of the last two production Multics systems -- the other one was at Credit Suisse, I think) years ago if you want to try it out. Still has the cryptic "hodie natus frater est" comment in the disk formatter code. 8-) ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
