I've always thought this was a serious omission in all of the package 
managers and that it would be really useful to be able to take any 
arbitrary machine that might have been carefully tuned for a specific 
purpose and 'publish' its package list.   Then anyone else who wanted a 
similar setup could tell his package manager to duplicate it without 
having to repeat the work of researching and choosing the package list. 
  It would be even better if you could 'subscribe' to a published list 
and track the exact versions installed on the master copy so you 
wouldn't do updates until you knew someone had tested the new version 
combinations already.
