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.

journalctl is the one part of systemd I really do not like. For whatever reason, it's insanely slow, taking multiple seconds before it gets around to display anything. It also has all the wrong defaults, displaying error messages from a year ago first, while scrolling to the bottom again also takes forever and consumes 100% CPU while doing so.
There are flags to filter and display only the relevant parts, but not only are none of them intuitive, doing a mistake there just gives you "-- No entries --", not an error. So you can never quite tell if you typed it wrong or if were are no messages.
Maybe it all makes more sense when studying the man page in depths and learned all the quirks, but /var/log/ kind of just worked and was fast, without any extra learning.
