Then I want to fork() a shell and do the usual: setuid(getuid()) Of course, I get EPERM, because setuid() is broken. Now is this a generic System V bug. I think it is. Clarification please? I think what I have is pretty generic SysV. V8 & 32V do the _right_ thing, they work. System V has, of course, a mind of it's own. I _know_ it's a bit silly, but it should _work_. UNIX did.
