Boot and Services

From power-on to the main menu

Firmware and kernelThe device firmware and kernel start the hardware.

StorageMustardOS mounts storage and prepares its runtime paths.

Hardware servicesInput and the essential hardware services start.

Display and audioThe display and audio routes are restored.

FrontendThe frontend launches and the main menu appears.

Networking runs on its own, separately from the main menu, so a slow or missing network never holds the frontend back. Services that need a network become available once an interface and address are ready.

Three kinds of location

/run/muosTemporary files the frontend, services and launch process use to coordinate. They are gone after a restart.

MUOSYour persistent choices, saves and content, kept on the selected storage.

/opt/muosRead-only application resources and programs.

Where Things Live lists every folder in detail.

Network Services covers the remote access services that start alongside the frontend.
