The original SteamOS-like Linux distro HoloISO now dead, replaced with immutable version

This seems more in line with how these OSs should be made IMO. I understand the point of Linux is to do whatever you want with it, but that's antithetical to the point of game ready operating systems like these. Especially when your average user is gonna be less Linux literate than other distros and can easily break something. It's also not like the read-only file system can't easily be modified by those who know what they're doing.
