[Libguestfs] Setting up guestfs mirrors

Thanks to the work by Jeff Layton, we've embraced guestfs on kdevops [0] as a replacement to vagrant. To save bandwidth kdevops lets you set up mirrors for all git trees we need, it would be nice to make it easier for folks to also setup mirrors for guestfs base images, the base images are here: https://builder.libguestfs.org/ I take it we'd just add say $XDG_CONFIG_HOME/virt-builder/repos.d/kdevops-local-mirror.conf with the new URL where we established the mirror, is that correct? I was looking to see if there was an rsync mirror for the main URL where all the images are above, or is there a better way to get the latest updates? Also, to save even more time with images, it would be useful if we had base images getting updates a bit more regularly so that the step to apt-get upgrade after bringup won't take too long by using the latest base images. It seems this is possible with customer images, but it would be nicer if we had this as a general thing. Any ideas to support that? [0] https://github.com/linux-kdevops/kdevops Luis
