Attempting to salvage a bad remaster...I copied a modified Knoppix filesystem over top of an existing one. Everything works but apt-get /dpkg packages list only shows the packages from the second (modified) system. The packages from the original system are still there but I can't remove or update them because they are not listed in the system packages list.
How can I get dpkg to search the system & make up a new packages list including all that is there? I tried dpkg -C, which is supposed to find partially installed packages, it didn't do anything.
