Creating a debian repository for squeeze and lenny

Hi guys,

Our company hosts packages of our own software on a local repository on our network. Right now it is what this guide refers to as a "trivial repository"

http://www.debian.org/doc/manuals/repository-howto/repository-howto

Our current development platform is Debian lenny, but we'd like to move to Debian squeeze. The problem is that our product's custom made packages, which we put into our local repo, are not compatible between the two. I have to tweak some dependencies and there are some minor code changes needed to make it work on squeeze.

Ideally, I'd like to make a fork of our project just for squeeze, and build "squeeze" specific packages.

How can I change the repository so that I have one set of "lenny" packages available for lenny machines, and another set of "squeeze compatible" packages are available for squeeze machines?

Below is an example of my sources.list:

deb http://ftp.ca.debian.org/debian/ lenny main
deb-src http://ftp.ca.debian.org/debian/ lenny main
# our local repository
deb http://192.168.1.55/mirror/repo binary/

Open in new window


And an example of the tree structure in our Repo:

repo
|-- binary
|   |-- Packages
|   |-- Packages.gz
|   |-- ourproduct_10.10-3057_all.deb
|   |-- ourproduct_10.11-3068_all.deb
|   |-- ourproduct_11.0-3160_all.deb
|   |-- ourproduct_11.2-3174_all.deb
|   |-- ourproduct_12.1-3188_all.deb

Open in new window


You can see how unlike the regular debian repos, our local one doesn't explicitly say "lenny" on it anywhere - so those packages show up no matter what version of linux we're using.

How do I change our local repository and/or my sources file so that I can make packages that differentiate between lenny and squeeze?

What is wrong in using automatic repositories from that same document?

You can follow this URL to see how debian does it..

Is creating the appropriate directory structure all that is necessary? I don't need to do any other fancy configuration of the package or anything like that?

it needs to be built for every environment of course.
And that might be more tricky than you think. If you need some feature from a library that is different from one set to another, that might give you a challenge.

(I used to have such problems in the past with RedHat, they provide a long term stable platform, but sometimes i need a faster moving platform and then there are conflicting libraries, depending on the mixed you need).
Esp. openssl might break between versions (by design, to prevent continued use of defective libraries).
