 Guix sources are in ~/repos/guix. FreeBSD sources are installed in /usr/src. Clone other helpful repos or extract sources to ~/repos/ as required.
 
+Note: Our goal is NOT to run Guix on top of FreeBSD, but more like to use it as inspiration for Fruix, which should embrace FreeBSD semantics - in the long run - like jails, bhyve, etc.:
+
+1. The model you want to preserve
+
+This is the real treasure:
+
+- declarative builds
+- content-addressed store
+- reproducibility
+- daemon-mediated privilege separation
+- garbage collection from roots
+- derivations as build descriptions
+
+That is the soul.
+
+2. The platform assumptions you should challenge
+
+These are not sacred:
+
+- Linux process/container assumptions
+- GNU coreutils/bash/findutils as ambient baseline
+- specific /proc or signal behavior
+- GNU userland quirks in package recipes
+- Linux-centric builder environment setup
+
+That is just sediment from history.

 Good luck!
