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.

Some executables are special. When you run them, they automagically run as root instead! But if sudo isn't very, very careful, you can trick it into letting you run things as root that you shouldn't be able to.

Run0 DM's systemd asking it to go fork a process as root for you, and serves as the middleman between you and the other process.
