In general, if you need debug symbols for something, I think it's OK to contribute adding them to Guix proper (in a debug output), unless they make like >= 1 GiB (as I can imagine may be the case for IceCat).

Channels can only extend, not override the default Guix channel (the world would be a bit of a mess if it did). So the easiest path is to use a different name; alternatively for graph rewriting you could use the various APIs to effect package transformations. > I know that we can specify version like "firefox@99" but what about > outputs? Is it possible to do (list "firefox:out" "firefox:debug").? I know nothing about GWL, but if it uses the Guix-provided specification->package procedure, it would work that way yes.n I hope that helps, Cheers! Maxim
