Great info Lennart (Christopher too).

My mother-in-law is still on dial-up and won't be changing anytime soon. 
I'd like to maintain her Ubuntu up-to-date, but it's nearly impossible 
to download the updates at those speeds. I would like to set up the very 
same Ubuntu release at home, then when I update my box, I'd make a copy 
of the new packages on a CD to take to her place once in a while.

I can see that the /var/cache/apt/archives would be the place to copy 
the packages from. Then it would be a matter of figuring out how to get 
her Ubuntu to search the CD for updates, would that be about right? Any 
complications other than trying to get the CD as an apt source?
