# Required Kernel Parameters:
#     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...

# WARNING... WARNING... WARNING...
# Additional kernel cmdline arguments that #may# be required to boot properly...
# add "vga=791 splash=silent,theme:default console=tty1 quiet" if you use a splash framebuffer ]
# add "dolvm" for lvm support
# add "dodmraid" for dmraid support
#       or "dodmraid=<additional options>"
