####################################################
# #
# This section contains configuration properties #
# #
####################################################
# This property defines the firmware compatibility, i.e. on which systems MLL
# will be bootable.
#
# bios - the generated ISO image will be compatible with legacy BIOS systems.
# This is the default option and it does not require root privileges.
#
# uefi - the generated ISO image will be compatible with UEFI systems. This
# option requires root privileges.
#
# both - the generated ISO image will be compatible with both legacy BIOS and
# modern UEFI systems. This option requires root privileges.
#
FIRMWARE_TYPE=bios
# Use predefined '.config' file when building the kernel. This overrides the
# config generation in 'xx_build_kernel.sh' and the build process uses the
# config file provided in this parameter. Place the configuration file here:
#
# minimal_config/kernel.config
#
USE_PREDEFINED_KERNEL_CONFIG=false
# Use predefined '.config' file when building Busybox. This overrides the
# config generation in 'xx_build_busybox.sh' and the build process uses the
# config file provided in this parameter. Place the configuration file here:
#
# minimal_config/busybox.config
#
USE_PREDEFINED_BUSYBOX_CONFIG=false
# Define the overlay type to use. Possible values are 'sparse' and 'folder'.
# You can use any other value, no value, or comment the property in order to
# disable it. Put your overlay content in the folder 'minimal_overlay/rootfs'
# and it will be automatically merged with the root file system on boot. The
# build process creates either '/minimal.img/rootfs' or '/minimal/rootfs' (read
# below) and this folder contains all overlay content in it. The build process
# also creates '/minimal.img/work' or '/minimal/work'. This folder is used by
# the overlay driver to store modifications related to the read only storage.
# If the overlay media is writeable, then all changes on the root filesystem
# are automatically persisted and preserved on reboot.
#
# sparse - use sparse file 'minimal.img' with hardcoded maximal size of 3MB
# (see 'xx_generate_overlay.sh'). The generated ISO image is larger,
# because the sparse file is treated as regular file. This option
# requires root permissions or otherwise sparse file generation is
# silently skipped. Sparse file is treated as separate disk image and
# works fine on FAT.
#
# folder - use normal folder structure (/minimal/). Note that this doesn't work
# if the file system is FAT because FAT requires special handling,
# e.g. POSIX overlay (http://sf.net/p/posixovl). This is the default
# option because it doesn't require root permissions.
#
OVERLAY_TYPE=folder
# This property defines one or more additional overlay software pieces which
# will be generated and placed in the directory 'work/overlay_rootfs'. These
# software pieces will be visible and fully usable after boot. Note that the
# build process for most of the overlay bundles depends on the softawre that
# is already installed on the host machine. The only overlay bundles that are
# guaranteed to work are the ones declared by default. The build process for
# most of the other overlay bundles may fail and therefore these bundles are
# not enabled by default. It is up to you to prepare your host environment and
# install all prerequisites for the overlay bundles that you want to build.
# For starters, you might want to install the 'libncurses-dev' library which
# is required by some of the overlay bundles.
#
# In the future Minimal Linux Live aims to provide fully functional 'sysroot'
# and all development host dependencies should be eliminated. However, for now
# it is up to you to maintain your host build environment.
#
# Note that if you build any overlay software and you are using sparse image
# file for the overlay structure then most probably something will go wrong,
# because the overlay software requires more than 3MB free space. The solution
# is to use folder overlay or to edit the script 'xx_generate_overlay.sh' and
# modify it to create sparse image file with bigger size.
#
# Currently available overlay software:
#
# all - all available overlay bundles.
# glibc_full - all core GNU C libraries.
#
# adopt_openjdk - JDK from AdoptOpenJDK with either HotSpot or OpenJ9.
# bosh_cli - BOSH CLI (command line interface).
# c2048 - console version of the game 2048.
# cf_cli - Cloud Foundry CLI (command line interface).
# cf_tools - all BOSH and Cloud Foundry tools.
# coreutils - set of commonly used GNU executable utilities.
# dhcp - DHCP and DNS functionality.
# dialog - shell scripting for ncurses
# dropbear - SSH server and client.
# felix - Apache Felix OSGi framework.
# fio - I/O load generator.
# golang - Google's Go programming language.
# graalvm - VM for Java, JavaScript, Python, Ruby, R, LLVM.
# kbd - keyboard utilities.
# kernel_modules - default MLL kernel modules and 'mdev' hotplug manager.
# kexec_tools - execute another kernel from userspace
# libevent - event notification library.
# links - text browser for the web.
# lua - scripting language.
# make - GNU make utility.
# mll_hello - simple educational overlay bundle. Type 'hello' to run it.
# mll_logo - custom MLL boot logo.
# mll_nikola - the meaning of life.
# mll_utils - set of executable utilities (mll-*).
# mll_source - MLL source code provided in directory '/usr/src'.
# nano - simple command-line text editor with on-screen shortcuts.
# ncurses - 'GUI-like' API that runs within a terminal emulator.
# nweb - simple mini http server.
# openjdk - installs Open JDK. All operations are automated.
# static_get - portable binaries for Linux (http://s.minos.io).
# stress - CPU and RAM load generator.
# util_linux - executable utilities distributed by the Linux Kernel org.
# vim - advanced text editor.
# vitetris - console mode tetris game.
# zlib - DEFLATE compression/decompression library.
# zulujdk - Zulu is certified build of OpenJDK with better support.
#
# Refer to the README file for more information.
#
# Each bundle can have separate '.config' file which overrides any property
# which has been provided in this configuration file. Refer to the README
# file for more information.
#
# The line below is sample which provides Open JDK, Apache Felix and Links.
# There is also network functionality provided by the 'dhcp' overlay bundle.
#
# OVERLAY_BUNDLES=dhcp,felix,links,openjdk
#
# The default overlay bundles are:
# * dhcp
# * mll_hello
# * mll_logo
# * mll_source
#
OVERLAY_BUNDLES=dhcp,mll_hello,mll_logo,mll_source
# The location where the overlay bundle software will be stored.
#
# rootfs - all overlay bundles will be embedded in the initramfs. In this way
# the software will be available on boot but the initramfs size may
# grow significantly and MLL will require more RAM in order to boot.
#
# iso - all overlay bundles will be packed in the ISO image structure. The
# actual location depends on the value of the configuration property
# 'OVERLAY_TYPE'.
#
OVERLAY_LOCATION=iso
# Always use local source bundles. This is useful when you have downloaded the
# sources and have no internet connection, or if you want to share your version
# of 'Minimal Linux Live' with predefined sources.
#
USE_LOCAL_SOURCE=false
# This property enables the standard penguin boot logo in the upper left corner
# of the screen. The property is used in 'xx_build_kernel.sh'. The default
# value is 'true' for demonstration purposes.
#
USE_BOOT_LOGO=true
# This property is the multiplicator which is used during the build process.
# The total number of each 'make' jobs will be equal to the number of detected
# CPU cores mutiplied by this property. For example, if you set this property
# with value '2' and if your CPU has 4 cores, then the number of 'make' jobs
# will be 4 * 2 = 8.
#
JOB_FACTOR=1
# This property defines the default GCC flags to be used during the compilation
# process. You can use your own flags here or even completely remove the flags.
#
CFLAGS=-Os -s -fno-stack-protector -fomit-frame-pointer -U_FORTIFY_SOURCE
