# Note that you do not have to rerun grub after making changes to this file
# NOTICE:   You do not have a /boot partition.   This means that
#           all kernel and initrd paths are relative to /, eg.

#           kernel /boot/vmlinuz-version ro root=/dev/sda3
#           initrd /boot/initrd-version.img
