As Phoronix had spotted earlier today, Distrobox – a wrapper that creates and uses containers (like a distro) that are highly integrated into the host machine – got a pretty big update with 1.4.0. I won’t go over the changes, but I will say this: there’s now documentation on how to get Distrobox set up on the Steam Deck. Just look under the “SteamOS 3” section on their table. Simply run steamos-readonly disable via the terminal to disable the immutable file system, then follow their installation instructions for Arch Linux or install Podman to $HOME.
