System administrators who believe users must prove that they need a service or resource before they will be permitted access to it have always annoyed me. When they get the upper hand, such administrators destroy user productivity by forcing the more numerous class of "users" to waste time proving when they should be using. When I have the opportunity, I try to challenge such *administrators* to prove that no users have a need before clamping down. "Prove to my you need it" is not the Unix way as I understand it. To quote from the forward of the original Bell System Technical Journal introducing Unix [volume 57, number 6, part 2], "He [Ken Thompson] and the others who soon joined him had one overriding objective: to create a computing environment where they themselves could comfortably and effectively pursue their own work ..." What resulted was a system that presumed openness, and restricted users only when there was a compelling need to do so. So, my challenge to you is, "Show me how the current kernel permissions can be used to crack FreeBSD." If you can't, please don't restrict them. If you must, please put mention of this change on a readme file list of gratuitous restrictions, so I can remove it from my systems without losing too much sleep over why it was there in the first place. -- David E.
