Nanami OS

Overview

Nanami is an experimental user-space OS built on A9N Microkernel. OS policy, drivers, filesystems, networking, graphics, and the Alter User-level OS Compatible Layer are implemented as separate user processes connected through capabilities and IPC.

Alpha, the initial user process, manages memory, processes, and service discovery. SPENCER integrates Nanami with A9N and A9NLoader-rs into a bootable UEFI image.

What it provides

User-space drivers and subsystem servers
An ext2 root filesystem and service manifests
IPv4 networking and socket services
The Honoka desktop and graphical shell
Alter User-level OS Compatible Layer

Role in the A9N Project

Nanami composes operating-system services and an application environment on A9N. It demonstrates how a complete system can be built above the microkernel without moving policy into the kernel.
