Hello, 

I built a modified version of Guix to have a series of custom Channels
by default. using this modified version, everything is OK, and I have
access to these custom channels by default.

The problem is that when I create a disk image using this custom build
of Guix, only default Guix channel  details is available during build, 
and I need to perform a `guix pull` to make the profile cache updated 
and install packages located in custom channels.

is there any way that allow me to have these custom channels available
by default in disk image?

I had seen that `gc-root-service-type` is responsible for preparing the
profile for disk image, but I don't know how can I configure it to have
additional data during disk image creation.

Just as a ping, does any one has any experience about embedding custom
channel stuff (packages, services) by default inside installation disk
image? 

regards,

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!
