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.

SELinux enters the chat
Sure you own it, your groups owns it, its permissions are 777, SELinux says GEEEEEEET FUUUUUUCKED.
Selinux is great. It provides actual security to a system
But it is hard to operate. Source: did more than audit2allow for years.
Honestly I've never had to do anything but the defaults so I can't really testify to that.
It's a bit of an ordeal on the server-side of things if you don't know what SELinux does. These days "is SELinux fucking something up?" is a regular on my troubleshooting list, though.
