When the last Debian release was coming up, I had deselect downloading from stable, frozen, and unstable. Then, some time ago, 'frozen' went away. This caused dselect to complain a lot when updating package lists. So, I just finished taking the 'frozen' parts out of all of my /var/lib/dpkg/methods/ftp/vars files on all of my servers when..... boom, 'frozen' is back.
So here's a thought: After each release, can we just keep 'frozen' pointed to the dist (ie, 'woody', 'potato', 'slink', etc.), even though 'stable' is also now pointing to it, too? - Joe
