# Full Build Result Caching (@kaspar030)

Idea: if a build fully succeeded, cache its *data* hash similar to the test result cache. When starting a build, check if there's already a full build that succeeded with the same data. This should skip rebuilds when only changing metadata, e.g., all squash builds.

Things to watch out for:
- take container/environment change into account

## progress

this *should* be trivial to add to murdock scripts. it is *not* trivial to test for lack of either test instance or access to production murdock. => postponed

09.11.21: renewed interest, will try in close collaboration with @tom
