My concern is regarding mirrors that aren't fully up to date (I've encountered the situation before and it wasn't a packaging error at the time) and reporting this fact to the user. Instead of using a time stamp, why not use a cryptohash of a list of the files installed as the lastsync value. Pacman -Syy could then check the hash value (it grabs from the tier 1 mirror) and check it against the current mirrors it's using. Regards, Mark -- Mark Lee <mark@xxxxxxxxxxxx>
