Oh fuck. I’ll use this from now on. Except for if I won’t use it next week. Then I’ll forget about it because my memory is a damn sieve.
Just take the next step and make a text file you dump all these commands into and then forget about in a week. When you randomly stumble across it years from now you’ll be able to say “wow, I could have used this 10 months ago if I remembered it existed!”
Well, systemd developers made one of the classic blunders a software developer can do: make a program that has to deal with time and dates. Every time I have to deal with timestamps I’m like “oh shit, here we go again”.
Anyway, as I understood it the reason this is in systemd is because they wanted to replace cron, and it’s fine by me because cron has it’s own brain-hurt. (The cron syntax is something that always makes me squint real hard for a while.)
I’m sorry but Cron is really easy, of all systems.
Try using systemd with an ssh server that you want to have running on a non standard port. On non systemd it’s a 15 second ordeal while on systemd I don’t even know where to start, I pushed it out of my memories. It’s something something create files here, restart demons there, removing other files, it is WAY WAY over complicated
What do you mean? You literally just change the
/etc/sshdconfig to point at a different port do you not?Oh yeah, without systemd that’s all there is to it. With systemd, however, port management is taken out of the ssh config and is done how it was decades ago
I run systemd with a different sshd service port and that’s all I changed
.Aube it’s distro dependent, but Ubuntu updated ssh a while ago to be passed through systemd. Updating the port requires systemd configuration changes
Systemd ignored my calendar override for the builtin raid scanner, so every week my server would chug to a halt to scan the entire array.
In true systemd fashion, the documentation could not explain this behavior, so I had to make a full copy override instead of a merge override because reasons.
Did setting OnCalendar to the empty string not work? https://unix.stackexchange.com/a/479745
Thank you for this, I am dumb when it comes to config merge rules because I’ve screwed up ALSA the same way
Okay this is cool and all, but why would systemd have a calendar?
(also how do i do this)
As others have said on this thread, it’s because systemd has fairly advanced timer system that basically requires implementing a calendar.
To do it, the command is in the screenshot
systemd-analyze calendar "Tue *-12-25".
me: systemd is not that bloated
systemd:
You need a calendar and time handling anyways for logging purposes and to set timers correctly. It’s likely not that much extra work exposing that functionality.
No, UNIX philosophy demands that every single one of those things is one or more separate things and that half of them are poorly or not at all maintained. Just like God intended.
Finding the next super holiday is a core system feature I could survive without. 🎉
