Currently, the guide states
"Edit the KEYMAP variable in /etc/rc.conf. Then either reboot or restart the keymaps script: /etc/init.d/keymaps restart."
However, wouldn't it be better to point the user to /etc/conf.d/keymaps instead of /etc/rc.conf?
This depends on baselayout 1.11 going stable.
Marking as LATER.
Closing this bug as per Josh's request in gentoo-doc's ML.
