Sabayon devkit

The Sabayon devkit is a set of scripts that aims to help developers in various tasks.

You can install it in sabayon with:

sudo equo i sabayon-devkit


  • docker installed in the machine (sudo equo i docker), and the daemon started (sudo systemctl start docker)
  • if you don't want to run that as root, the user where are you running the script must be in the docker group (sudo gpasswd -a $USER docker), or granting permission to yourself adding your user to the sudoer file.

Packages can be built in a clean environment with docker by running sabayon-buildpackages.

sabayon-buildpackages and ``sabayon-createrepo are just a script wrapper around the development docker container.

Define your workspace

Create a directory to represent your project workspace.

cd $HOME
mkdir myproject
cd myproject

if you plan to make packages from your own ebuilds, and you don't have an overlay published in layman, you can create the local_overlay directory and put your overlay tree inside it.

me@box:myproject/$ mkdir local_overlay

myproject/local_overlay is read from the docker container and mounted inside it as the local overlay available in the machine.

If you want, you can define the workspace directory with the variable environment SAB_WORKSPACE

SAB_WORKSPACE=/whatever sabayon-createrepo

Folder structure

This is the folder structure of your workspace by default, but you can tweak part of it to your tastes with Environment variables:




  • myproject/portage_artifacts/ -- Created when sabayon-buildpackages is started. It contains the portage artifacts, they will be consumed in the next steps
  • myproject/entropy_artifacts/ -- Created when sabayon-createrepo is started. It contains the entropy repository files.
  • myproject/local_overlay/ -- is the location of your personal overlay (if necessary)
  • myproject/specs -- Create it to customize the building process. It can contain custom files for make.conf, uses, envs, masks, unmasks and keywords for package compilation options

the specs folder is structured like this and it's merely optional.

as long as you create those files they are used:

  • custom.unmask: that's the place for custom unmasks
  • custom.mask: contain your custom masks
  • custom.use: contain your custom use flags
  • custom.env: contain your custom env specifications
  • custom.keywords: contain your custom keywords
  • make.conf: it will replace the make.conf on the container with yours.

you can override the Architecture folder in which files are placed specifying in the SAB_ARCH environment variable. Default is "intel" (can be armarch as for now)

Note: the portage_artifacts can also contain tbz2 files generated with other methods, if you already have your desired packages already compiled, you can just use sabayon-createrepo

Building package in a clean environment

sabayon-buildpackages accepts the same arguments as the builder:

sabayon-buildpackages app-text/tree
sabayon-buildpackages plasma-meta --layman kde
DOCKER_PULL_IMAGE=1 sabayon-buildpackages app-foo/foobar --equo foo-misc/foobar --layman foo --layman bar foo
  • --layman foobar -- tells the script to add the "foobar" overlay from layman
  • --equo foo-misc/foobar -- tells the script to install "foo-misc/foobar" before compiling

Environment variables:

  • DOCKER_PULL_IMAGE -- tells the script to update the docker image before compiling, enable it with 1, disable with 0
  • OUTPUT_DIR -- optional, default to "portage_artifacts" in your current working directory, it is the path where emerge generated tbz2 are stored (absolute path)
  • LOCAL_OVERLAY -- optional, you can specify the path to your local overlay (absolute path)
  • REMOTE_OVERLAY -- optional, a space separated list of overlays that can be cloned with git.

The arguments are the packages that you want compile, they can be also in the complete form e.g. =foo-bar/misc-1.2

Create Sabayon repository from *.tbz2 in a clean environment

You can create Sabayon repositories from packages built with emerge in a clean environment with docker by running sabayon-createrepo.

The script will use a docker container to inject packages from portage_artifacts/ in your project folder, the output will be available in entropy_artifacts/.



REPOSITORY_NAME=mytest REPOSITORY_DESCRIPTION="My Wonderful Repository" sabayon-createrepo
  • REPOSITORY_NAME -- optional, is your repository name id
  • REPOSITORY_DESCRIPTION -- optional, is your repository description
  • PORTAGE_ARTIFACTS -- optional if you use the tools in the same dir, you can specify where portage artifacts (*.tbz2 files) are (absolute path required)
  • OUTPUT_DIR -- optional, you can specify where the entropy repository will be stored

You can also put your .tbz2 file externally built inside entropy_artifacts/ in your workspace folder (you can create it if not already present) and run sabayon-createrepo to generate a repository from them.

In both sabayon-createrepo and sabayon-buildpackages you can override the docker image used with the environment variable DOCKER_IMAGE.
