That is fragile because `fpm` is not safely concurrent with itself and can fail due to file-system collisions. Furthermore, if the multi-image execution is implicit (e.g. controlled by environment variables), then even if `fpm` succeeds it can result in a quadratic number of executing images (8x8 = 64 concurrent images in the example).\n\nThis should be simplified to ensure we never concurrently invoke the same `fpm` command.","author":{"url":"https://github.com/bonachea","@type":"Person","name":"bonachea"},"datePublished":"2025-06-30T22:14:41.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/59/assert/issues/59"}
