“The Depthboot base distros all allow image/iso/rootfs sharing, but only in an unmodified form. The Depthboot script customizes some internal distro behavior (for example it adds our eupnea packages) and thereby creates modified images. To allow modified images to be shared, all trademarked content would have to be removed, i.e. all Distro logos.”
Why don't they use some hosted workers (GitHub Actions, GitLab Runners) to do the job?
