archlinux: reinstall

[Tim Chase]

This page is where I got my answer:

https://wiki.archlinux.org/index.php/Pacman_tips#Backing_up_and_retrieving_a_list_of_installed_packages

There's a section on AUR/yaourt backup/restore at the bottom of that
section, but I don't do much with Arch, so I can't say I've tried
them.
