Here's my /boot/grub/grub.conf: box0 linux # cat /boot/grub/grub.conf # This is a sample grub.conf for use with Genkernel, per the Gentoo handbook # http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=10#doc_chap2 # If you are not using Genkernel and you need help creating this file, you # should consult the handbook.
