From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

In what way does selinux allow your users to lock themselves out of their own home directories in a way that the admin can not fix?
SElinux is a "global ACL." You can stop root from doing anything you like with it. Usually by accident and without realizing it's been done in my experience...
No, that is just not true. You can stop root from doing things without a reboot with SELinux but encrypting something with a password root does not know actually does stop them from doing it at all short of a brute force attack on the encryption.
That's true - you can often recover a bad ACL. I was thinking more of the "niche use case" where separating duties and restricting root are concerned.
Oh, I was specifically thinking that admins that have users either competent enough not to forget/lose their passwords or mature enough not to whine to the admin when that causes the loss of all their files are pretty niche.
