ObsidianOS is an Arch-based Linux distribution that implements A/B partitioning for safer system updates and rollbacks, similar to ChromeOS and Android. The distro features experimental Rust-based tools including user-mode overlays for layered filesystem modifications and opm, a package manager that creates overlay images. It offers multiple editions (Base, KDE, COSMIC, and Void) with a custom Qt6 installer. While still young and experimental, it addresses system reliability without relying on btrfs snapshots or complex rollback mechanisms, making updates dramatically safer through simple partition switching.
