I would like to set up my own Ubuntu distribution such that it is always updated with the latest stable releases of every single package I have. Since stable Ubuntu point releases are always a bit late in terms of latest packages (which is understandable), I cannot do this with standard PPAs. I wonder if there is a method to do this automatically. I'm thinking of a few options:
Add a list of external PPA with the latest packages. Would this work for all applications? Do all applications have their own stable-latest PPA?
Create my own PPA, to be automatically updated (possible?) with new releases. Apparently, you cannot create a PPA in launchpad with unmodified packages (like a database of other people's packages). So this is not possible?
Use Synaptic Package manager? These seems to be quite flexible, allowing for latest releases. But it might not have access to all packages.
Writing a script that detects when new stable releases are available, and that can download and install new releases. This could be based in information from Launchpad, extracting information using Scrapy? This seems to be the optimal option. It might require considerable time to code, but it could turn out to be a nice script that can be transformed later into an app.
Please advice.
