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.

Very cool. I had no idea systemd sort of has a cron replacement. While in I don't think I'll switch from cron in the immediate future, it's really good to know.
Systemd timers are way, way better than cron. Because can audit them, view when they last run, next expected run, can be set to persist with reboot or not, aggregate logs under journalctl, can do amazing things such as "x minutes after boot", can be configured not to run again until the last run is complete etc... https://opensource.com/article/20/7/systemd-timers
You can do most of that with cron as well https://man.archlinux.org/man/fcrontab.5.en. If you want details about successful runs I think you would have to ensure you always logged.
