I did some small changes to pkg_add to detect the "updatedb" (cache for package updates) in a way that's independent from quirks.
Soon, quirks will gain an @option updatedb entry. If you have old pkg_add (e.g., you don't update to a snapshot of base before a package snapshot) this will break as a syntax error. Soon afterwards, you will lose caching entirely... Please update. (the idea is to move the updatedb to a separate package, so "being quirks" is not enough to identify the db, and it's cleaner to do it as a unique-option. I'm committing this in stages, so people who follow the rules should not be impacted at all... :-> )
