The CPC team wants to reenable the repo-snapshot-stamp feature in magic proxy to get similar package sets when building multiple images. But that is currently broken.
When building in launchpad with something like:
RUN: /usr/share/launchpad-buildd/bin/in-target buildlivefs --backend=lxd --series=impish --arch=arm64 LIVEFSBUILD-299827 --project ubuntu-cpc --datestamp 20210924 --image-format ext4 --image-target disk-image --image-target kvm --image-target qcow2 --image-target squashfs --image-target tarball --image-target vagrant --image-target vmdk --image-target azure --image-target azure-pro --image-target hyperv-gcs --image-target wsl --repo-snapshot-stamp 1632467595 --cohort-key MSAqIDE2MzI0Njc4OTcgMTVjNTk1ZWQ1NjFlMjM5OWEzNmQ5ZTE0MDlmZjlmMDdiOGNhM2JlMGI0N2UyMzBjZGVjMGUzOWEyNjk0NTA1Mw==
the build fails with:
REDIRECT tcp opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 tcp dpt:80 ! owner UID match 1 redir ports 8080
