Why would a debian image make this faster? ubuntu is quite fast already when things are cached properly (see this run https://github.com/commaai/openpilot/actions/runs/12645418288/job/35234526525)

Thanks for taking a look. I'm not sure what exactly is slow about the existing setup. I didn't see the ~1m4s run time quoted in the original Issue.

The setup is slow for many reasons, for examples the image is way too big and we don't have great/fast caching on Github
