Thanks, Luke, is there any documentation about how to do that? After save the live-cd in the USB, what should I do? I have three partitions in disk: /dev/sda1 for /, /dev/sda2 for /home and /dev/sda3 for /var (extra partition for swap).

How _exactly_ I have to install missing packages?. I'm a newbee

I rely on pacman --ignore <foo> installs only packages without foo dependency.

I don't know. I don't remember. I have in pacman logs. If I could see them, I'll show you
