Fortunately, the SONAMEs in Knot DNS changed, so knot-resolver shouldn't break based on a simple upgrade. right? Or are the lua bindings going to ignore SONAMEs somehow? This is an update to knot-resolver -- but it seems like the fix is in kind of the wrong place. Shouldn't the the zs_scanner struct lua definition live in the knot-dns package, so that it can be upgraded concurrently? Thanks for highlighting this change! I need to think about how we best avoid this kind of breakage during sequenced upgrades in debian, so any pointers to details about how lua and SONAMEs and struct definitions interact would be most welcome. At the moment, i'm just aiming to keep older versions of knot-resolver from building against knot-dns 2.8.0 like so: https://salsa.debian.org/dns-team/knot-resolver/commit/5709b37c29ce88c19fb0… (which will of course change if i backport the proposed patch in question) Any thoughts about better ways to do that? All the best, --dkg
