The MOS project is currently in development, creating a lightweight modular Linux distribution based on Devuan Linux. This distribution is specifically designed for managing home servers. Initially created for personal use, the project has now expanded beyond individual needs and has been made available to the public. The latest release, version 0.1.9-beta, supports only UEFI boot mode. Installation images have been prepared for USB drives (354 MB) and for launching in virtualization systems (348 MB).
MOS is positioned as a versatile server operating system with a user-friendly web interface. Following the API-first principle, the web interface functions as a client to the backend REST API, with all operations carried out by server services. Real-time notifications are delivered using WebSockets. The project is distributed under the AGPLv3 license and does not collect telemetry data or send information externally. The minimum requirements for running MOS in a virtual machine are 2 CPU cores and 6 GB of RAM.
Out of the box, MOS comes equipped with support for mergerfs for combining multiple disks into a single pool, as well as SnapRAID for data protection using checksums parity based on snapshots. Additional storage and hardware drivers (such as GPU and DVB) can be added through a plug-in system. The MOS Hub component provides access to a catalog of plugins and templates.
Containerization in MOS is implemented through Docker and LXC, while virtualization is handled by QEMU. Services can be activated and deactivated independently, allowing for a minimalist installation. A separate service called MOS Notify has been developed for notifications. Authentication in MOS is token-based, with TLS and reverse proxy recommended for operation outside isolated networks.
