Re: Automated /etc/config.scm

[David Larsson <david.larsson@selfhosted.xyz>]

Hi Marek,

I think its not possible to have guix pull edit /etc/config.scm without modifying how that command behaves in guix.

But it is possible to edit /etc/config.scm when running guix system reconfigure, by using a service as described here:
 https://lists.gnu.org/archive/html/help-guix/2017-08/msg00095.html

Though perhaps that's not exactly the answer you are looking for?

If you want to be able to push new configs to some channel git repo and have that reflected in a target host after a guix pull + reconfigure from the host, then I can suggest adding system configuration variables in the channel referring to the various systems you want to deploy. Then adding minimal config.scm files on the deploy targets. Those config.scm files can have '(use-module (mychannel my-systems))' or similar, and then just '%my-os-system1', etc on the final line.

I hope it helps, but not sure.

Regards,
David
