Nitrux Update Tool System

NUTS is the update and rollback utility for Nitrux. It performs atomic system updates while preserving the ability to restore the previous state.

How it Works

1. Creates a backup of the root partition using xfsdump.
2. Downloads an OTA-style archive and applies the update atomically.
3. Rollbacks are performed offline from a Live session using xfsrestore.

NUTS operates on the root filesystem as a whole rather than managing individual packages. It has no package index, cache, or dependency resolution—it replaces the immutable root with a new version.
