Bedrock Linux: a meta Linux distribution

Bedrock Linux is a meta Linux distribution which allows users to mix-and-match components from other, typically incompatible distributions. Bedrock integrates these components into one largely cohesive system.

You think you've seen everything the Linux world has to offer and nothing can you surprise you anymore, and then you run into something like this. I wonder how well this works if a Bedrock Linux installation holds up over time.
