This is different from Bazzite and some of the other SteamOS similar operating systems by being as close to vanilla SteamOS as possible.
According to the devs:
It’s a SteamOS based distribution that is intended to be as close to 1:1 compatible with upstream SteamOS as possible while making changes to support a wider range of hardware. It originated as a fork of HoloISO but it has been majorly overhauled to eliminate things like post-copy operations (as much as possible), introduce our own signed package repositories, add an automated release process, and provide many bug fixes and refinements. The focus has largely been on handheld gaming consoles, but it’s in use on a variety of AMD based mini PCs as well.
As cool as a new entry into the landscape is, this one still has the same filesystem limitations as SteamOS. That’s not necessarily a bad thing, but I do wonder how this one will meaningfully distinguish itself from the others.
