Where can we start? :) Anyone can be experiment with this in Copr now (see the chroot/project/build "bootstrap" configuration options). Any publicly available podman image can be used to initialize the bootstrap. > I wonder how much slower it is? With --use-bootstrap-image, the host's package manager isn't involved in preparing the bootstrap at all. E.g. for the fedora-33-x86_64 chroot 1. 'fedora:33' container image is downloaded (this can be cached on builder) 2. container is executed from the image to install 'dnf-plugins-core' (needed by mock, we could skip this step if we had a complete image). 3. the container content is exported to /var/lib/mock/<chroot>-bootstrap/root and from now on it is normal "bootstrap" (pkg management tools from there are used to install normal chroot). So we could make the bootstrap image feature overhead almost instant (equivalent to extraction of several-tens-of-MB image/tarball extraction), if we maintained the special image you talked about. IOW, bootstrap image is even now slightly faster than normal bootstrap, but we could make it almost as fast as mock without bootstrap.
