Modify Channels for all users

Modify Channels for all users

[Reza Alizadeh Majd]

Hi Guix, 

I want to add a custom channel for all users, one way would be using the skeleton files 
to add `channel.scm` to each user's home directory. Just wanted to know if there is 
any other solution to do this or not? 

Thanks
Reza

You could try to modify a %default-channels variable in
guix/channels.scm file.  See how to build Guix from Git in
https://www.gnu.org/software/guix/manual/html_node/Building-from-Git.html

modifying %default-channels variable, needs guix image to be rebuilt. 

it might be helpful if we had a reference about channels in system 
configuration file. maybe guix development list would be a better place 
about this matter to discuss. 

Thanks,
Reza

I think a skeleton for ~/.config/guix/channels.scm is a good way to
achieve this.

I just aware about that copying the skeleton files is a one time operation, we can't modify 
skeleton files later with a new system configuration file for existing users. do we have any 
solution to copy skeleton files to existing users home directories   on each execution of 
guix system reconfigure ?

Thanks ,
Reza

If you modify these files at each reconfigure, they’re no longer
skeletons.  :-)  I would advise against it.

Now, you could very much add an “activation snippet” that forcefully
copies files to the user home directories at each boot.
