  "message": "Fix Linux VM image creation and handle gcloud SQLite concurrency collisions (#2769)\n\n### Summary of Changes\n\n1. **`buildkite/create_images.py`**:\n- Use machine type `c4a-standard-8` for the `bk-testing-docker-arm64`\nimage builder VM. Local SSDs (`-lssd`) are ephemeral, not captured in\ncustom GCE images, and caused capacity stockouts\n(`ZONE_RESOURCE_POOL_EXHAUSTED_WITH_DETAILS`) in `us-central1`.\n\n2. **`buildkite/gcloud.py`**:\n- Add automatic retry for transient `gcloud crashed (OperationalError)`\n/ SQLite schema migration collisions when multiple threads invoke\n`gcloud` concurrently.\n- Example failure:\nhttps://buildkite.com/bazel-trusted/create-linux-vm-image/builds/43#019ff552-6791-4b7a-95c4-2c7c882bcfd5",
