lichen

A heavily in-development, experimental, and early days installer for AerynOS. A privileged backend (lichen_backend) provides all the relevant logic and functionality, while a frontend (cli) provides a user interface for the installer.

Additional frontends will be added in the future, but the cli frontend is the reference implementation using the installer workflow/control crate.

All communication is performed asynchronously over a Unix domain socket, using gRPC as the protocol. See crates/protocols for the protocol definitions.

Eventually we'll support TCP sockets for remote installations, empowering a WASM frontend for web-based installations, and more. Before then we need to get our ducks in a row (and add Polkit middleware checks for the backend, etc).

Much of the code is powered by our disks-rs project, including disk enumeration, analysis, provisioning and dynamic disk strategies.
