Sabayon stuff for build Sabayon Official Images.

Sabayon team currently build ISO images through Mottainai tasks that are available here and in particular for stable ISO see iso path or for development ISO see iso-dev path.

Hereinafter, how build ISO images in two steps:

1. Check Host System:

• Docker Service must be active
• Check support of kernel for squashfs with xz compression
• Check that all tools needed are available:
  • cdrtools
  • mktorrent-borg
  • postfix (optional and needed for send email)
  • squashfs-tools
  • dev-util/molecule-core
  • dev-util/molecule-plugins

2. Start building through sabayon_iso_build.sh script.

$# ./scripts/sabayon_iso_build.sh

Sabayon ISO Image Build Script.

./scripts/sabayon_iso_build.sh [action] [opts]

Valid actions: daily, weekly, monthly, dailybase, release.

Available options:

-h|--help               This message.
--pull-skip             Skip pull of docker image
--skip-dev              Skip build of development images (with limbo repository).
--skip-export           For development avoid export of docker image if it is already
                        present.
--only-dev              Build only development images.
--docker-rmi            Enable clean of orphaned Docker images.
--image [NAME]          Build only a specific image. (This option can be used multiple time).
                        Valid value are:
                          * spinbase
                          * gnome
                          * kde
                          * mate
                          * minimal
                          * xfce
                          * lxqt
                          * tarball
                          * gnome-forensics

Environment variables to customize:
SABAYON_DOCKER_SRC_IMAGE
                        Default to sabayon/spinbase-amd64:latest
SABAYON_UNDOCKER_OUTPUTDIR
                        Default to /sabayon/sources/amd64-docker-spinbase.
MOLECULE_TMPDIR         Default to /var/cache/molecule
SABAYON_MOLECULE_HOME   Default to /sabayon
SABAYON_KERNEL_VERSION  Set kernel slot to install on image.
                        Default is 4.14
SABAYON_EXTRA_PKGS      Define additional packages to install
                        on spinbase rootfs.
SABAYON_SOURCE_ISO      Define source ISO to remove from iso directory.
SABAYON_SOURCE_ISO_DEV  Define source ISO-dev to remoe from iso directory.
SABAYON_UNMASK_PKGS     Define additional packages to unmask.
SABAYON_MASK_PKGS       Define additional packages to mask.
SABAYON_ENMAN_REPOS     Define additional enman repository to install
                        on spinbase rootfs.
DRACUT                  Enable Dracut. Default is 1 (enable).

NOTE: Every ISO images are based on spinbase rootfs, so to customize kernel version (that must be available on Sabayon Repository) it is needed build also spinbase ISO image because override of last available kernel is done on inner_script of spinbase image.

After build is done ISO images are available under iso directory.

// Get molecules sabayon data
$# git clone https://github.com/Sabayon/molecules.git
$# cd molecules
// Became root
$# sudo su

// Now you can build ISO
$# SABAYON_MOLECULE_HOME=`pwd` ./scripts/sabayon_iso_build.sh daily

Build daily spinbase image with kernel 4.9:

$# cd molecules
$# SABAYON_KERNEL_VERSION=4.9 SABAYON_MOLECULE_HOME=`pwd` ./scripts/sabayon_iso_build.sh \
      daily --image spinbase --logfile /tmp/sabayon-build.log \
      --stdout --skip-dev --pull-skip --skip-email

Option --pull-skip can be used when is already available on local Docker image.

Build daily Gnome image with kernel 4.9:

$# cd molecules
$# SABAYON_KERNEL_VERSION=4.9 SABAYON_MOLECULE_HOME=`pwd` ./scripts/sabayon_iso_build.sh \
      daily --image spinbase --image gnome --logfile /tmp/sabayon-build.log \
      --stdout --skip-dev --pull-skip --skip-email

Build daily Gnome image with additional packages:

$# cd molecules
$# SABAYON_KERNEL_VERSION=4.9 SABAYON_MOLECULE_HOME=`pwd` \
      SABAYON_EXTRA_PKGS="app-emulation/lxd games-strategy/wesnoth" \
      ./scripts/sabayon_iso_build.sh daily --image spinbase --image gnome \
      --stdout --skip-dev --pull-skip --skip-email

Build daily Gnome image with additional packages from gaming-live community repository:

$# cd molecules
$# SABAYON_KERNEL_VERSION=4.15 SABAYON_MOLECULE_HOME=`pwd` \
      SABAYON_EXTRA_PKGS="media-libs/mesa-9999 x11-libs/libdrm-9999" \
      SABAYON_ENMAN_REPOS="gaming-live" \
      ./scripts/sabayon_iso_build.sh daily --image spinbase --image gnome \
        --stdout --skip-dev --pull-skip --skip-email

Main difference between iso with dev extension is related with type of repository used for create image: dev use limbo repository otherwise sabayon-weekly it is used.
