| Fixed In Version: | Doc Type: | Bug Fix | ||
| Doc Text: |
Cause: images younger than the threshold are not added to the dependency graph.
Consequence: a blob which is used by a young image and by a prunable image is deleted because it has no references in the graph.
Fix: add young images to the graph and mark them as non-prunable.
Result: the blob has references and is not deleted.
