So the issue was whether quotas were handled trough the kernel or 'find / -user nobody'? And it was connected to the System-V/BSD split? Learn something new every day. Makes sense. My memory must be getting foggy, though; I thought when I was working on such things, chown worked (for users) on SunOS 4.x (4.2BSD), but not Solaris 2.x (SVR4). But I must be remembering it backwards. -- jay -------------------------------------------------- This email and attachment(s): [ ] blogable; [ x ] ask first; [ ] private and confidential daggerquill [at] gmail [dot] com http://www.tuaw.com http://www.dpguru.com http://www.engatiki.org "This has been your orientation.
