Automatic mirror rewriting: Every 5 days your Arch/CachyOS mirrorlists will be regenerated automatically. If you maintain custom mirrorlists (e.g., pinned to a local/corporate mirror, or a specific country), this timer can overwrite that and cause unexpected routing, different repos, or compliance issues.
Offline / flaky networks: If the timer runs while you are offline or on a bad connection, mirror updates may fail or produce a suboptimal mirrorlist, impacting future update performance until fixed manually.
So, if this is a new configuration in CachOS or whatever, will this change potentially lead to more problems than it solves? Was this change announced somewhere?
It’s always a trade-off. You follow the forums, so you might have noticed that many of the recent problems have been solved by updating the mirror list.
I don’t think it will introduce more errors. If you really want to manage your mirrorlist manually, you’re always free to do so.
A sensible default is updating the list automatically.
I also use custom mirrors and don’t want them changed.
But when i tried to disable the service, I got a wierd error. So I ended up stopping both the timer and service, and then masking both the timer and the service.
I like to do all my updates manually and I filter out certain countries in my mirrors.
