But they arent.
Just ask someone from Iran or China.
They have different uses … and I certainly dont want to overwrite the 5 mirrors I have chosen to use when all I want is to rank their current status.
Further … you have this wrong…
Its not … the recommended update is
pamac update
or if you use pacman
sudo pacman -Syu
Anything else is extra fluff for one reason or another … if you dont understand why you would or would not add to those commands … then you should stick to those basics.
For one thing … doing pacman-mirrors and -Syyu every update is just an unecessary tax on the mirror servers. So dont, unless you have a good reason.
