## What it is
Moss is a Unix-like, Linux-compatible kernel written in Rust and AArch64 assembly, featuring an asynchronous kernel core and a modular hardware abstraction layer. It can run dynamically linked Arch Linux AArch64 userspace binaries such as bash, BusyBox, and coreutils.

## Use cases
- run Linux userspace binaries on a Rust-written kernel
- study kernel development using async/await in Rust
- experiment with an AArch64 operating system kernel
- learn how Linux syscall compatibility is implemented
- research deadlock-free locking via compiler-enforced async rules
- port a kernel to new architectures via a HAL

## When to choose
- you want a Rust-based research or hobby kernel with real Linux binary compatibility
- you're exploring async/await patterns inside kernel space
- you target AArch64 hardware or emulation

## When to avoid
- you need a production-grade kernel with full syscall and driver coverage
- you require x86_64 or RISC-V support today
- you need stable filesystem write support across ext4 and other filesystems

## Facets
- artifact type: application
- maturity: experimental
- function: embedded, concurrency
- domain: operating-systems, developer-tools
- platform: rust, embedded
- tags: kernel, rust-kernel, aarch64, linux-compatible, async-kernel, unix-like, operating-system, linux
