Building Hyperscale images with mkosi

This repo contains a simple mkosi config that will build a bootable Hyperscale image. By default, a CentOS Stream 9 image is built. To create a CentOS Stream 8 image, add -r 8 when running mkosi. mkosi 19 or newer is required.

To build the image, clone the mkosi repository and run the following commands:

mkosi -f # Build the image
sudo mkosi boot # Boot the image in systemd-nspawn
mkosi qemu # Boot the image in qemu

To test new rpm package builds, create a file mkosi.local.conf and configure the BuildSources= setting to mount your systemd source tree in the systemd/ directory and the rpm repository in the systemd/rpm directory. For example:

[Content]
BuildSources=../../systemd:systemd
             ../rpm/systemd:systemd/rpm

mkosi will then build the latest version of the rpm and install it into the image (except for standalone, devel and tests packages).
