  "message": "m/test/launch: build image at runtime\n\nTest launch now builds the node disk image from the OCI image, instead\nof creating a qcow2 snapshot of the pre-built disk image. This speeds up\ntests and test cluster launch.\n\nThe OCI image is uncompressed and payloads are not verified, which\nenables the previously implemented copy_file_range optimization. If the\nhost file system supports reflinks, this has a similar effect as the\nqcow2 snapshot had previously: Building the image is very fast as the\nrootfs data is not copied on disk. On my machine, it takes 30 ms.\n\nThe build before launching a cluster is now faster: The MkImage step\ntaking 6 s is replaced by MkOCI taking 1 s. The majority of this time is\nspent by Bazel computing hashes of files. For MkImage, the generated\nfile was a 5 GB disk image consisting mostly of zeroes, which took a\nlong time to hash.\n\nAdditionally, the qcow2 layer added some overhead, which is now gone.\nThe HA e2e test previously took 103 s on my machine, now it takes 80 s.\n\nChange-Id: I0ce5059626cc682061c26ac3c8d11b752e641c60\nReviewed-on: https://review.monogon.dev/c/monogon/+/4294\nTested-by: Jenkins CI\nReviewed-by: Tim Windelschmidt \u003ctim@monogon.tech\u003e\n",
