TITLE:		Compiling your keymap into the kernel
LFS VERSION:	All
AUTHOR:		Matthias S. Benkmann <m.s.b at gmx.net>

SYNOPSIS:
	By default the Linux kernel sets a US keymap. That's nice for people
	with US keyboards but if you don't use one, you need to run loadkeys
	to set the proper keymap. This is no big deal if you boot normally
	because you have a boot script to do this, but if you boot with
	init=/bin/sh, or into single user mode, this boot script is not
	started and you will have to start loadkeys (by typing "loadkezs" on
	a qwertz keyboard) manually which, depending
	on your setup, may require mounting filesystems first.
	But it need not be like this. You can compile the appropriate
	keymap into the kernel to get the same native keyboard support,
	US keyboard users get. 

HINT:

When you have reached the "Making the LFS system bootable" section in the
end of the LFS book, right before compiling your Linux kernel, do the 
following:

Tell the kernel about your keymap by running the following commands:

     cd /usr/src/linux &&
     dumpkeys | loadkeys -m - >defkeymap.c &&
     cp defkeymap.c drivers/char/defkeymap.c

This assumes that the currently active keymap is the one you want to use. 
If you want to use a different keymap instead, issue the following 
commands:

     cd /usr/src/linux &&
     loadkeys -m /path/to/keymap >defkeymap.c &&
     cp defkeymap.c drivers/char/defkeymap.c

Replace `/path/to/keymap' with the full path to the appropriate
keymap file (usually located in a subdirectory of /usr/share/kbd/keymaps).
       
Now you can compile your kernel as usual. If you follow these instructions 
you don't need the loadkeys boot script and /etc/sysconfig/keyboard file
(they will still work, of course).
