From Thin Air to Bootable Images: The tine Build System
Amutable introduced tine, a Buck2-based build system for producing reproducible operating-system images and their components from pinned inputs. It runs builds in hermetic environments, supports RPMs plus Rust and Go components, signs images, and can generate SBOMs.
The notable design choice is using Buck2’s content-addressed actions and declared “boxes” as build environments, rather than treating image creation as a special-purpose pipeline. The post contrasts that model with mkosi, BuildStream, OBS, and Antlir, then demonstrates producing and booting a Fedora image. This is a new project announcement; its claims about reproducibility and build properties are from the authors.
