no, /etc/guix/channels.scm also functions as a default channel list for every
users’ `guix pull`, which I also want to have.

This snippet:

---snip---
(simple-service 'guix-channels etc-service-type
   (list `("guix/channels.scm" , (scheme-file "channels.scm" %guix-channels))))
---snap---

Causes this error when reconfiguring:

---snip---

/gnu/store/mdpbph8cpgwydy3hwfq0q6sk44bfbk93-etc looks correct to me, i.e. it
has a guix subdirectory with a correct channels.scm file in it.

Cheers,
Lars
