Hermit-rs is a Rust-based unikernel (library OS) that enables applications to run directly on hardware or hypervisors without a traditional operating system. The repository provides the build infrastructure (the `hermit` crate), the system call ABI (`hermit-abi`), and a collection of example applications demonstrating networking, file systems, TLS, WASM execution, and more. The actual kernel is maintained in a separate submodule. The project is actively developed with CI testing across x86_64, aarch64, and riscv64 architectures, and supports running under QEMU, Uhyve, and KVM. It is a hybrid of a system library and an application framework, but its dominant character is an application platform for building unikernel images.
This repository is the build system for AvyOS, a Linux distribution that compiles all packages from source using a custom Go-based tool called 'ignite'. The system defines hundreds of YAML recipes under `elements/` for building the kernel, system libraries, desktop environments (KDE, GNOME, Xfce, Sway, etc.), development toolchains, and applications. The ignite tool handles dependency resolution, source fetching, containerized builds (via bubblewrap), and image generation (ISO, disk images, OSTree commits). The architecture is a declarative recipe system with reusable includes, patch management, and a web dashboard for monitoring builds. Key entry points are the `ignite` CLI and the YAML recipe files. External dependencies include upstream source tarballs, patches, and a custom build environment. The repository also includes configuration for secure boot, A/B updates, and live ISO booting. While the codebase is well-structured and demonstrates significant engineering effort, it is a personal project with limited documentation, many TODO comments, and potential drift due to custom kernel versioning and future-dated Go version requirements.
