While that may make the combination simpler, the extra copy involved here is making things inefficient. Why would piuparts need two temporary chroots? It should just be using the one mmdebstrap prepared and be happy with that. So I do think we need a new piuparts option that explains how --existing-chroot should work: * Copy the chroot as a template. * Actually use it directly. While we often want the former, in this case, we want the latter. Without an extra option, piuparts will be unable to tell those two cases apart and always use it as a template. Helmut
