# 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=========

# Should we install to $BOOTDIR?  Default is "no" because genkernel is used in
# catalyst and stage building.
INSTALL="yes"

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

# Run 'make menuconfig' before compiling this kernel?
MENUCONFIG="yes"

# Run 'make clean' before compilation?
# If set to NO, implies MRPROPER WILL NOT be run
# Also, if clean is NO, it won't copy over any configuration
# file, it will use what's there.
CLEAN="no"

# Run 'make mrproper' before configuration/compilation?
MRPROPER="no"

# Override the arch detection?
#ARCH_OVERRIDE="x86"

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

# Make symlinks in BOOTDIR automatically?
SYMLINK="yes"

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

# Use Color output in Genkernel?
USECOLOR="yes"

# Clear build cache dir
#CLEAR_CACHE_DIR="yes"

# Clear all tmp files and caches after genkernel has run
#POSTCLEAR="1"

# Genkernel uses an independent configuration for MAKEOPTS, and does not source
# /etc/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="-j5"

# Add in LVM support from static binaries if they exist on the system, or
# compile static LVM binaries if static ones do not exist.
LVM="yes"

# Add in Luks support. Needs sys-fs/cryptsetup with -dynamic installed.
LUKS="yes"

# Add in GnuPG support
GPG="yes"

# Add DMRAID support.
DMRAID="yes"

# Include (or suppresses the inclusion of) busybox in the initrd or initramfs.
# If included, busybox is rebuilt if the cached copy is out of date.
BUSYBOX="yes"

# Includes mdadm/mdmon binaries in initramfs.
# Without sys-fs/mdadm[static] installed, this will build a static mdadm.
MDADM="yes"

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

# Add Multipath support.
#MULTIPATH="no"

# Add iSCSI support.
#ISCSI="no"

# Add e2fsprogs support.
E2FSPROGS="yes"

# Include support for unionfs
UNIONFS="1"

# Enable copying of firmware into initramfs
FIRMWARE="yes"
# Specify directory to pull from
FIRMWARE_DIR="/lib/firmware"
# Specify specific firmware files to include. This overrides FIRMWARE_DIR
#FIRMWARE_FILES=""

# Enable disklabel support (copies blkid to initrd)
DISKLABEL="yes"

# Add new kernel to grub?
#BOOTLOADER="grub"

# Enable splashutils in early space (initrd). Default is "no".
SPLASH="yes"

# Use this splash theme. If commented out - the "default" name theme is used.
# Also, SPLASH="yes" needs to be enabled for this one to one work.
# This supersedes the "SPLASH_THEME" option of /etc/conf.d/splash (in early space).
SPLASH_THEME="gentoo"


# =========Keymap Settings=========
#
# Force keymap selection at boot
#DOKEYMAPAUTO="yes"

#KEYMAP="0"


# =========Low Level Compile Settings=========
#

# command line option.
#KERNEL_CC="gcc"

# Assembler to use for the kernel.  See also the --kernel-as command line
# option.
#KERNEL_AS="as"

# Linker to use for the kernel.  See also the --kernel-ld command line option.

# GNU Make to use for the utilities.  See also the --utils-make command line
# option.

# Compiler to use for the utilities (e.g. distcc).  See also the --utils-cc
# command line option.

# =========GENKERNEL LOCATION CONFIGURATION============
# Variables:
#   %%ARCH%%  - Final determined architecture
#   %%CACHE%% - Final determined cache location

# Set genkernel's temporary work directory.  Default is /var/tmp/genkernel
#TMPDIR="/var/tmp/genkernel"

# Set the boot directory, default is /boot
#BOOTDIR="/boot"

# Default share directory location
GK_SHARE="${GK_SHARE:-/usr/share/genkernel}"

# Location of the default cache
CACHE_DIR="/var/cache/genkernel"
# Location of DISTDIR, where our source tarballs are stored
DISTDIR="${CACHE_DIR}/src"
# Log output file
LOGFILE="/var/log/genkernel.log"
# Debug Level
LOGLEVEL=1

# =========COMPILED UTILS CONFIGURATION============
#

#BUSYBOX_CONFIG="/path/to/file"

# NOTE: Since genkernel 3.4.41 the version of
#   busybox, lvm, mdadm, .. have been moved to
#   /usr/share/genkernel/defaults/software.sh in order to
#   reduce the merging you have to do during etc-update.
#   You can still override these settings in here.

# keeping it as a separate file
#INTEGRATED_INITRAMFS="1"


# Compress generated initramfs
#COMPRESS_INITRD="yes"
# Types of compression: best, xz, lzma, bzip2, gzip, lzop, fastest
