you don't need buildkite or blacksmith anymore.

codex trivially built me a self-hosted gh actions runner workflow for ephemeral vm's (just a big bash script that manages the vms with qemu). i even sped up the builds with my own custom base image with everything installed in it that i need too.

it works flawlessly.

fanning that out to starting and stopping instances wouldn't be too much of a stretch.
