Arch Linux ARM
Did not use Arch Linux ARM, for now, because some of the packages are broken (like CUPS, which is super important to this task). Maybe if I find some time I'll debug this, but for now I've switched to using Raspbian which is a Debian derivative.
Installation is super-easy. Just follow the raspi-setup program to setup common services (SSH, keyboard layout, locales). If you live in the US it's strongly advised to use this setup program to set the locales and keyboard layout. If you don't the keyboard may not work as expected.
