I have multiple machines running Debian 6 (Squeeze) and 7 (Wheezy). I set up an Apt-Cacher server on a Debian 7 box, for the Debian 7 instances to use. Can this also be used (with the same wheezy sources.list) by the Debian 6 instances?
I copied the sources.list from the Debian 7 box to the Debian 6 box, and forgot to change the wheezy references back to squeeze. Then I did an apt-get update and an apt-get upgrade on the Debian 6 box, and of course it got all of the Debian 7 packages and upgraded. Have I broken that Debian 6 box now?
I would be very grateful of some clarification on how the package repositories work with different versions - are they entirely separate?
