Hi. Would it make sense that the special protections in preinst preinst are only done when upgrading from a version < 13.4, which is the version in which some directories became symlinks and vice-versa?
This would have the advantage that in cases like this one the upgrade would happen as normal without prompting the user (the dangling symlink would continue to be a dangling symlink). The con would be that an anomaly of the x32 setup would remain hidden. I think it would be correct to assume that most people who will execute the preinst will do so when upgrading from bookworm to trixie, so I would agree that the difference between those two options would be quite small. Thanks.
