The thing I like about using #freedesktop sdk for a base for #Bluefin is yes, it's a #linux distribution.
But fsdk products can guarantee that its purpose will always be application developers since that's the reason it exists. That's what we mean by "distroless". You just talk move the thing that used to be important into CI and then it all becomes about the payload. The libraries application developers need with all the guarantees they expect, with the understand that THEY are the stakeholder, we're sysadmins FOR THEM.
Also for app developers it's the easiest path to SteamOS and Bazzite. This what we mean by "distributions don't matter".
The entire point is for users to not deal with any of this crap.
