I think we should keep libvirt at compat 8 in general for now and then leave a full bump to compat 12 for bullseye. The reason here being that the compat changes documented in debhelper(7) amounts to 3-4 screens worth of changes across all of debhelper's tools. Instead, we can do a mixed compat setup, where the package remains at compat 8 in general but we force selected tools to run in compat 12. I have made a PoC of that in https://salsa.debian.org/libvirt-team/libvirt/merge_requests/21/diffs Note that change set is only meant as inspiration; I have not tried to understand the problem nor the solution fully (nor have I tested that it actually still builds). Thanks, ~Niels
