Ehh to snaps. That would 100% be the first thing of support to drop if I were them. That said it cool to see more immutable distros experimenting, I wonder how much overlap there is the Kalpa since it is btfs based.
Honestly there definitely still seems some good space for innovation in the immutable space before we “figure it out”, so the more smart people experimenting the better!
I am not an expert but I don’t think Snap support can be added to an immutable distro after installation, meaning there is going to be some software that simply cannot be easily installed. Snap support is basically a legacy support feature at this point but I think it’s nice to cover their bases if they are trying to make something for widespread adoption.
