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.

Everybody gangsta until
A start job is running for ... (10s / 1min 30s)Or, even worse,
A start job is running for ... (10s / no limit)lol, that brought back memories
I don't see how exactly that is systemd's fault.
You are blaming it for having proper dependency handling?
I'm blaming it for making it a pain in the ass to debug dependency problems and for having the confusing, non-intuitive, overly verbose and redundant syntax that probably caused the problem in the first place.
Like, who the hell can memorize all the subtle differences in behavior between
After=,Requires=,Wants=,Requisite=,BindsTo=,PartOf=,UpHolds=and then all their "reverse" equivalents?You're right that the difference isn't overly obvious. However, for most services,
Wants=is enough. I think some of these (likeRequisite=) 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 especiallyUpheldBy=is a smart addition; it adds restarting to a service only if that services is used as a dependency for the one it upholds.
