How to Build an Image

There are several different ways to build an image.

How to setup Xorg

Install the xorg and xf86-video-scfb packages, and add the following to /etc/X11/xorg.conf:

Section "InputDevice"
    Identifier  "Keyboard1"
    Driver      "kbd"
EndSection

Section "InputDevice"
    Identifier  "Mouse1"
    Driver      "mouse"
    Option      "Protocol"      "auto"
    Option      "Device"        "/dev/sysmouse"
EndSection

Section "Monitor"
    Identifier  "Monitor"
