Additional UML tests could be specified. Just as an idea. I did some CI testing for LKRG on GA, https://github.com/lkrg-org/lkrg/blob/main/.github/workflows/docker-boot.yml https://github.com/lkrg-org/lkrg/blob/main/.github/workflows/docker-boot.sh It's possible to boot in QEMU system created in Docker (alas without KVM as GA does not support it). But this will install distribution's kernel. So it would need to find distribution with the appropriate kernel. Also, GA have cache functionality, so there could be dependent job to build the kernel with required options and then save it into a cache (to save time, bandwidth, and CPU resources). And another possibility is, instead of using Docker it's possible to use cloud images that many distributions have, and then same as with docker (install or build kernel, save into cache and use in next CI runs). Never tried this method myself. AFAIK this will require to use cloud-init to set up system on first boot. Thanks, > > thanks, > > Mimi
