#     real_root=/dev/$ROOT

#     Where $ROOT is the device node for your root partition as the
#     one specified in /etc/fstab
#
# If you require Genkernel's hardware detection features; you MUST
# tell your bootloader to use the provided INITRAMFS file. Otherwise;
# substitute the root argument for the real_root argument if you are
# not planning to use the initramfs...
