udevadm info --cleanup-db cleaned links and tags by comparing them against /run/udev/data, but asserted when that data directory was missing. Treat a missing data directory as an empty database, so stale link and tag entries can be removed without aborting. Add a database test that runs cleanup-db with links and tags present but no data directory. Reproducer: $ sudo unshare --mount --propagation private sh -c ' mount -t tmpfs tmpfs /run/udev mkdir -p /run/udev/links/foo udevadm info --cleanup-db ' Assertion 'datadir' failed at src/udev/udevadm-info.c:676, function cleanup_dirs_after_db_cleanup(). Aborting. Aborted (core dumped) The command should handle a missing /run/udev/data directory instead of aborting.
