I recently installed smartmontools from a third party rpm and had trouble seeing the updated man pages because there were cached versions of the old ones. I think the problem was that the cached man pages were timestamped with when they were created (not when the man pages they were derived from were created) and the newly installed man pages had a timestamp from when they were created for the rpm (not when they were installed) so that the cached pages still had a later timestamp than the new pages. Is there some documentation on the proper way to install man pages from an rpm so that any cached version of the man pages will be treated as out of date? (Or possibly the rpm should just remove the cached versions?)
