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
You can download the latest release from github and run it in the virtual machine of your liking.
For QEMU the following command is recommended:
qemu-system-x86_64 -enable-kvm -M q35 -m 2g -cdrom astral.iso
There are a few targets in the makefile to run Astral with qemu when built from source:
make run
make run-kvm
make run-disk (if you built the disk image)
make run-disk-kvm (if you built the disk image)
