You could use use the output of 'dpkg --get-selections' on the Sid
boxes, pruning it using grep or similar to keep only the lines ending
with 'install'. Combine the results from the various Sid boxes, and
then have the gateway box get those packages. This could be scripted
easily enough, and there would be no need for manually updating
anything.
