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.

It's a massive question, and I think quite a lot of the argument comes from the fact that it depends what direction you're answering it from.
As a user, do I like being able to just
systemctl enable --now whatever.service
, and have a nice overview of 'how's my computer' insystemctl status
? Yes, that's a big step up from symlinking run levels and other nonsense, much easier.As an administrator, do I like having services, mounts and timers all managed in one way? Yes, that is very nice - can do more with less, and have to spend less time hunting for where things are configured. Do I think that the configuration files for these are a fucking mess of 'just keep adding new features in' and the override system is lunacy? Also yes.
As a developer trying to do post-mortem debugging, who just wants all the logs in front of him for some server that's gone wrong somehow, which I often have to request via an insane daisy-chain of emails and 'Salesforce nonsense that our tech support use' from our often fairly non-technical end users, on some server that I've no other access to? No, I do not find having logs spread between
/var/log
and journalctl (and various CloudFormation logs in a web console) makes my life easier. I would be pleased if that got sorted out.tl:dr; mostly an improvement, some caveats.
I didn't know that logging question is related to SystemD, so thanks for telling it! As an non-top class desktop user the same thing frustrates especially because the solution is often simpler and not found from those logs.
