Hmm I understand the need here, but at the same time, the variable is
called ‘%default-channels’ (plural) to preserve the ability to turn
splut Guix into several channels.

What could work though is your patch, except with the name
‘%default-guix-channel’ instead of ‘%default-channel’, which makes it
clear that it’s just the ‘guix’ channel.

Works for you?

Thanks,
Ludo’.
