OpenBSD image builder

An OpenBSD image builder.

Or a love letter to OpenBSD made with blood sweat and tears.

Or one way tame Qemu and autoinstall using Python's asyncio.

TL;DR

./openbsd build disk.img
./openbsd ssh disk.img

Design goals

• Configuration-less: playground for reluctant hackers
• Audit-trail friendly: the specification file controls everything
• Run in unprivileged mode: no more sudo
• Minimal dependencies: newish Python (>=3.11) and Qemu, i.e. no pip only standand library
  • optionally signify and socat
• Cloud friendly: upload and register the images as AWS AMIs
• Stable over time: convenient (read: doable) to add new versions (or old versions?)
