I asked how to rediscover what packages are "really new" after you change your sources.list and everything shows up as new in this message: http://lists.debian.org/debian-user/2004/debian-user-200401/msg05571.html Aaron Hall suggested: http://www.debian.org/News/weekly/ I'm using that, but I've another question: What files on my hard drive do apt-cache reference to display that information? Perhaps if I back those up daily and later diff them.
