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.

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.
