Yes, but that’s okay: the ‘.guix-channel’ file has a syntax that looks
similar but is different from that of ‘~/.config/guix/channels.scm’, as
you explained (and as the manual explains, I think.) This is on
purpose.
I understand it might look confusing but I’m not sure there’s much we
can do.
Thoughts?
