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. :)
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
Fully agreed. But I know how to use cron, I have a life to live, and this switch is way down the priority list.
But it is something I’d like to find the time to do at some point.
Well if it makes you more comfortable let me tell you that the format of
OnCalendaris the same, or very close. I bet that just by looking at the following you know what is does![Unit] Description=Logs some system statistics to the systemd journal Requires=myMonitor.service [Timer] Unit=myMonitor.service OnCalendar=*-*-* *:*:00 [Install] WantedBy=timers.targetYou 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.
