Gentoo Genkernel Config

# Configuration file for genkernel

# This file is sourced by genkernel at startup and determines which options
# we will be using to compile our kernel.  The order of precidence is simple,
# with the internal settings being least important, configuration file
# settings next, and command line options being most important.

# =========Common Command Line Option Defaults=========

# Install to $BOOTDIR
#INSTALL="yes"

# Run 'make oldconfig' before compiling this kernel
#OLDCONFIG="yes"

# Run 'make menuconfig' before compiling this kernel
#MENUCONFIG="no"

# Run 'make gconfig' before compiling this kernel
#GCONFIG="no"

# Run 'make nconfig' (ncurses 'menuconfig') before compiling this kernel
#NCONFIG="no"

# Run 'make xconfig' before compiling this kernel
#XCONFIG="no"

# Run 'make mrproper' before compiling this kernel
#MRPROPER="yes"

# Run 'make clean' before compiling this kernel
# Only needed if MRPROPER is set to NO because
# MRPROPER implies 'make clean'.
#CLEAN="yes"

# Mount BOOTDIR automatically if it isn't mounted
#MOUNTBOOT="yes"

# Make symlinks in BOOTDIR automatically
#SYMLINK="no"

# Save the new configuration in /etc/kernels upon
# successful compilation
#SAVE_CONFIG="yes"

# Enable color output in genkernel
NOCOLOR="false"

# Clear build cache dir on gernkernel start
#CLEAR_CACHEDIR="no"

# Clear all tmp files and caches after genkernel has run
#POSTCLEAR="no"

# Check for x MB free disk space in BOOTDIR
#CHECK_FREE_DISK_SPACE_BOOTDIR=0

# Check for x MB free disk space in kernel outputdir
#CHECK_FREE_DISK_SPACE_KERNELOUTPUTDIR=0

# Genkernel uses an independent configuration for MAKEOPTS, and does not source
# /etc/portage/make.conf . You can override the default setting by uncommenting
# and tweaking the following line. Default setting is set up by
# ${GK_SHARE}/${ARCH_OVERRIDE}/config.sh . The recommended value for -j
# argument is: <number of processors>*<number of cores per processor>+1
#MAKEOPTS="$(portageq envvar MAKEOPTS)"
MAKEOPTS="$(portageq envvar MAKEOPTS)"

# Run the kernel make at the following NICE level
#NICE=10

# Possible values: empty/"no", "all", "intel", "amd"
#MICROCODE="all"
MICROCODE="intel"

# Include early microcode in generated initramfs.
# Only needed if system cannot load multiple initramfs.
# NOTE: >=sys-boot/grub-2 will detect and auto-load {amd,intel}-uc.img file
#       provided by sys-firmware/intel-microcode[initramfs] or

# if the cached copy is out of date.
#BUSYBOX="yes"

# Add MDRAID support
#MDADM="no"

# Specify a custom mdadm.conf.
# By default the initramfs will be built *without* an mdadm.conf and will auto-detect
# arrays during bootup.  Usually, this should not be needed.

# Add Multipath support
#MULTIPATH="no"

# Add iSCSI support
#ISCSI="no"

# Add e2fsprogs support

# Run "emerge @module-rebuild" automatically when possible and necessary
# after kernel and modules have been compiled
#MODULEREBUILD="yes"

# Run the specified command in the current environment after the kernel and
