I use not only guix chan, but nonguix (for the binary build system and for clojure-tools)
gorilla (for babashka as binary build; I also use it for vs-codium, but this is currently broken due
to core update merge) I dont think I use repos from guix-science in this profile.
This is the output of "guix package --export-manifest"
;; This "manifest" file can be passed to 'guix package -m' to reproduce
;; the content of your profile. This is "symbolic": it only specifies
;; package names. To reproduce the exact same profile, you also need to
;; capture the channels being used, as returned by "guix describe".
;; See the "Replicating Guix" section in the manual.
