It's been bludgeoned into behaving like SystemV, and BSD extensions have been turned back on over time, with POSIX stuff added in even later. Most of the SysV commands are used so that HP-UX passes the SV validation suite. (Their boot-up copyright message thus displays everyone's names.) The networking code is, of course, from BSD. HP also supported the now-defunct CSRG group at Berkeley for quite a long time, supplying both hardware and money. Features from BSD eventually found their way into HP-UX, notably fixes and enhancements to the networking code. The Domain/OS vs HP-UX thing was largely political, as was the OSF mess, and what happened to DUX (HP's distributed hetrogenous clustered Unix). (If you don't know, please don't ask - it's too depressing to discuss.) -- Parag Patel <parag@netcom.com>
