To be clear, you don’t just want a predefined /etc/guix/channels.scm,
you want the actually channel bits as returned by ‘guix pull’, right?

This is currently not easy to do out of the box, but here’s a couple of
tricks to more or less do that:

  
https://git.savannah.gnu.org/cgit/guix/guix-artwork.git/tree/website/.guix.scm#n42
  https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/ci.scm#n265

The 2nd one in particular would allow you to treat a “pulled Guix” as a
package.

HTH!
