DebOS

DebOS is a tool to make the creation of various Debian-based OS images simpler. While most other tools focus on specific use-cases, DebOS is designed to be a toolchain making common actions trivial while providing enough rope to do whatever tweaking which might be required behind the scenes.

DebOS expects a YAML file as input and runs the actions listed in the file sequentially. These actions should be self-contained and independent of each other.

Some of the actions provided by DebOS to customise and produce images are:

• apt: install packages and their dependencies with 'apt'
• debootstrap: construct the target rootfs with debootstrap
• download: download a single file from the internet
• filesystem-deploy: deploy a root filesystem to an image previously created
• image-partition: create an image file, make partitions and format them
• ostree-commit: create an OSTree commit from rootfs
• ostree-deploy: deploy an OSTree branch to the image
• overlay: do a recursive copy of directories or files to the target filesystem
• pack: create a tarball with the target filesystem
• pacman: install packages and their dependencies with pacman
• pacstrap: construct the target rootfs with pacstrap
• raw: directly write a file to the output image at a given offset
• recipe: includes the recipe actions at the given path
• run: allows to run a command or script in the filesystem or in the host
• unpack: unpack files from archive in the filesystem
