Really cool!
This is a killer feature IMHO compared to the Dockerfile approach. Let
spread the world. ;-)

Hello Guix! This patch series allows ‘guix system’ to record provenance info about a system in its output: the system itself (e.g., /run/current-system) now contains three more files: “channels.scm”, “configuration.scm”, and “provenance” (a summary of the first two files.) That means you can always inspect a deployed system to find its own “source”. In some cases, you can even run something like: guix time-machine \ -C /var/guix/profiles/system-N-link/channels.scm -- \ system reconfigure \ /var/guix/profiles/system-N-link/configuration.scm to rebuild generation N of your system. Pretty cool, no? :-) Otherwise you can simply run: guix system describe to see where your OS comes from. Provenance tracking is implemented as a service. The service is automatically added by ‘guix system init’, ‘reconfigure’, and by ‘guix deploy’. For other commands, one can pass ‘--save-provenance’ to turn it on. This was long overdue! This has interesting implications on trustworthiness: you can distribute a VM/Docker image with provenance info, and anyone can reproduce it and ensure they obtain the same bits (well, ideally, because I guess a few steps may still not be bit-reproducible). Thoughts? Thanks, Ludo’.
