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.

Worse, it preserves "special" files like the ones in /dev or /var which aren't removable by anyone other than root. Love extracting a system file backup in my file server as a regular user in order to get just a few files out of it, and promptly not being able to fully delete it afterward without SSHing into the server and using sudo.

I don't get how a regular user can even create files like that. Sounds like a security vulnerability.
