After a while of no updates to the actual ISO download of HoloISO, the creator of this SteamOS-like Linux distribution has announced the original is now dead. As it's being replaced by the newer immutable HoloISO.
If that was their intention I wouldn't blame them either but Valve said it would become available for other manufacturers to use when the steam deck was first announced
Isn't the secret sauce already available, with the issue being that it's not adapted to run on a wider range of devices? I had the impression HoloISO was just that, but as a community project - putting in all the work to make it installable on various devices (and work correctly)
I would imagine they would want a smooth experience on steam. That is the point of all of this work after all , so releasing the image gets more devices shipped with steam and more users into their ecosystem.
"We're hoping soon, though, it is very high on our list, and we want to make SteamOS more widely available. We'll probably start with making it more available to other handhelds with a similar gamepad style controller. And then further beyond that, to more arbitrary devices. I think that the biggest thing is just, you know, driver support and making sure that it can work on whatever PC it happens to land on. Because right now, it's very, very tuned for Steam Deck."
