Arch maintenance script

It's a good idea to keep your system well maintained. Arch has a wiki article in which they describe best practices on how to maintain your Arch system according to them.

So I went through the article and found that some of these things I already do, like updating my system and packages, or removing orphaned packages. But other things I rarely do, like checking if systemd services have failed. So I decided to cherry-pick a number of actions I think are great and put those in a little bash script, which I could then run from time to time in order to keep my system running smoothly for years to come.

sudo mv mirrorlist /etc/pacman.d/mirrorlist

# Done
