Well, mounting floppies is likely to be an issue at all only on desktop systems. Quite likely the user *is* the administrator, and just doesn't want to become root more often than necessary. So I don't see much harm in telling people how to do this.... especially since I couldn't find vfs.usermount in the sysctl man pages either. Just my opinion, of course.
