@liw I'm not sure how I will install Guix. The only thing I know is that I will not go through an installer, neither GUI nor TUI.
For NixOS, I had a declarative configuration, and I used nixos-anywhere to install it. No human input, fully automatic, fully scripted. Wasn't exactly fast, because it downloaded a ton of binary packages - but the bottleneck was my bandwidth. That's an acceptable bottleneck.
My plan is to do something similar with Guix. Like you, I want (nay, will have) a scripted, reasonably fast installation.
The experience will be documented in a blog post.
