- OS developers and systems programmers
- Worth noticing
- Its self-hosting test builds a Ferrix image inside the guest, then boots that image.
Field notes
Tests are launched with `cargo xtask test-rustc` and `cargo xtask test-selfhost`: the first compiles and runs a program in the guest; the second builds a Ferrix image there and boots it. The regular boot suite checks allocator and memory-map behavior, multi-processor coordination, and deliberately failing cases. A separate crash-during-write test remounts btrfs and runs the host's `btrfs check`; the page reports 249 seeds.
