bty mascot

bty

Flash operating system images onto target disks.

(Pronounced "battie", rhyming with "batty"; the blue bat up top is the mascot.)

CI Documentation PyPI Container Changelog

bty writes OS images to bare metal, offline from a USB stick or networked over PXE, scaling from one machine to a rack on one runtime. The image is the source of truth: rebuild the image, reflash the target, with no imperative configuration management. bty is a flasher, not an image builder, so pair it with one such as safl/nosi.

Documentation

Install, the USB / portable-catalog / PXE-server delivery shapes, the bty-web HTTP API, and ORAS-published images and catalogs all live at:

→ https://safl.dk/bty

Ecosystem sidecars

The container deploy runs bty-web alongside two sibling services that are built and released independently:

  • safl/withcache -- URL-keyed artifact cache; bty's preferred image-bytes source.
  • safl/nbdmux -- HTTP-controlled NBD-export multiplexer that serves boot_mode=ramboot targets.
