rwfus
A read-write overlay filesystem that enables using pacman on Steam Deck without losing packages after system updates.
What is rwfus?
Rwfus is a read-write overlay filesystem tool specifically designed for the Steam Deck. It solves the problem of package management on SteamOS's immutable root filesystem by overlaying critical directories, allowing users to install and retain Arch Linux packages via pacman across system updates.
Steam Deck users who want to install additional Linux packages without unlocking their device or dealing with complex system modifications, particularly those needing simple, persistent package management.
Developers choose Rwfus for its simplicity and direct approach to enabling pacman on Steam Deck, offering a lightweight alternative to more complex solutions like Nix while explicitly warning about limitations for advanced use cases.
