Fedora 40 Change Proposal: Systemd Security Hardening
(discussion.fedoraproject.org)
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.

Damn security guys are trying to justify their existence again.
My Fedora is single user and the system handily comes with one called 'root'
This is good for precisely the single user case - potentially malicious services on your system can't view things they otherwise would be able to, or access resources they don't need. Even if it's under the same user.
Can't tell whether you are joking or not
