Do you have any experience/scrips creating a controlled APT proxy (*)? Currently, I'm using apt-cacher to speed up installs/updates in my LAN, but as its name says, it's only a cache (and a good one for my needs). The only drawback is that I don't know how to freeze a specific set of packages for the cache/repository to control updates. Almost certainly, apt-cacher isn't the right tool for this jobs so, any help would be appreciated.
Thanks in advance,
Humber
(*) An APT repository that has only specific packages and updates to control the OS that uses that repository. I named this way because I don't know if it has another name
You can create your own apt repo with reprepro debian (ubuntu?) package, and then add the repo's url to the sources.list of client boxes.
