Right, it's not guaranteed to match the channel name, but it's 
usually enough to deduce it.

I meant something like:

  λ guix show nicecat | grep ^location
  location: nckx/packages/gnuzilla.scm:105:2

Because my channel uses (nckx packages ...) module names.  Most 
channels do something similar.

If you're using a third-party channel that shadows (clobbers?) the 
(gnu packages ...) namespace, I'm not sure what you could do.

Kind regards,
