The main mproblem is that archlinux mirrors are huge:
and archlinux itself count on the experienced user to manage it to his needs… i do use only around 20 from the archlinux mirrors, and i do a regualr update to my lists.
It would be possible to automate this, as i use an alias for it so that i only need to type
upgrade inside terminal and it runs this:
alias upgrade="sudo fetchmirrors -q -s 16 -c DE && sudo sh ~/reflector-antergos-v3 && sudo pacman -Syy && yaourt -Syua"
and reflector-antergos-v3 is a script written by @manuel ;) (yes manuel i still use v3! )
As i think this will be not harmfull to stability, i can think of an systemd-timer ? so you can simple enable and disable it…
But also the alias is very handy, as you can run it if you have problems with lame updates .
