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.

Systemd: Hidden Gems for a Better Linux (tadeubento.com)

After a few conversations with people on Lemmy and other places it became clear to me that most aren't aware of what it can do and how much more robust it is compared to the usual "jankiness" we're used to.

In this article I highlight less known features and give out a few practice examples on how to leverage Systemd to remove tons of redundant packages and processes.

And yes, Systemd does containers. :)

You're right that the difference isn't overly obvious. However, for most services, Wants= is enough. I think some of these (like Requisite=) came from actual users' demands where they had to solve corner cases in their setup that systemd did not allow with the existing features. I think especially UpheldBy= is a smart addition; it adds restarting to a service only if that services is used as a dependency for the one it upholds.
