Adding dokeymap Support

Before proceeding, this requires some knowledge of Catalyst.

Steps to Setup

IMPORTANT If you wish to use your own specs, make sure your dracut command-line args follow the ones I have in my spec files.

Rebuild Catalyst with the patch in portage/patches so it automatically adds cdroot to the boot args
Add package.use and savedconfig in portage/ into the appropiate folders in Catalyst's portage confdir
Make a stage1, I've added one to this repo for conveinience
Copy 90dokeymap into the stage1 chroot at /usr/lib/dracut/modules.d/
Copy keymaps into the stage1 chroot at /lib
Proceed with making a stage2, if you used the one provided, no editing is needed

In the portage/ directory there are the directories:

package.use is used to set savedconfig on sys-apps/busybox so we can use a custom config for it

patches contains a patch that will automatically append cdroot to dracut's boot args

savedconfig contains a config for sys-apps/busybox that will allow us to use loadkmap

This is a dracut module that will display the list of keymaps and allows the user to select one

Taken from genkernel, this is the list of keymaps it has available

spec files I used to save time for testing.
