I was wondering if this was influenced by Nix. I believe they're really on to something with that system, but it's tremendously tricky to use at this point in time.
Bedrock Linux wasn't influenced by Nix. When I started working on what ended up being Bedrock Linux, I wasn't familiar with Nix. Both projects are going about things in very different manners. Nix's is a lot cleaner, but will take a lot more manpower or time to get to the point where I could use NixOS as my primary system. I agree that they're on to something - I'd love for Nix project to take off.
