Not necessarily for merging:
- 1. missing tests
- 2. snapshot format adaptation is only needed for staging as previous runs
occurred (so it has snapshots with an old format).
I've patched the current nixguix deployed on staging with the following fixes:
- Some sources.json entries can be inconsistent and missing their integrity
field. Filter out the entries without 'integrity' key for now. The fix should
be upstream in the sources.json though.
- Account for possible unresolvable revision given the new snapshot format.
