Why is nobody else questioning the need for an option to "repair permissions"? Permissions (basic file rights) are the fundaments of a secure system. Or (for example) a properly setup company fileserver with sensitive information that not every employee needs to know. If my file rights structures on many of my clients Novell Netware servers would get corrupted or changed by simply using it and installing some software on it. I would have a lot of angry clients and I'd be talking to Novell Techsupport about what the f*ck is going on. So why do the permissions on Mac OS X get corrupted so easily? Maybe some UNIX guys can shine light in my eyes, because I feel that I must be missing something important in my reasoning here. But I can't figure out what.
