Having a prompt to skip rate-mirror on update would be great.
Running rate-mirror on each garuda-update often takes longer than the actual update itself and doesn’t really give any benefit unless something has changed since the last time it was run.
You could uncomment SKIP_MIRRORLIST=1 and UPDATE_AUR=1 in /etc/garuda/garuda-update/config, and then just run plain old garuda-update every time if you wanted.
Either way, sudo is not needed when running garuda-update.
