Building

The build process only needs xorriso, curl, zstd, fakeroot and bsdtar on the host. If you wish to use the make img option, you will need mtools. All other needed packages will be installed/built on the container.

To build the project, run make. This will create a file named astral.iso

After this, if you wish to create an ext2 disk image, run make disk

Running

If you built it from source, run make run-kvm or make run-disk-kvm

There are prebuilt images and instructions at https://astral-os.org/about.html.
