Does 'guix describe - f channels' always return a list of all of 
the user's channels? If I include a channels.scm file in a 
project, it would be nice if it only contained the channels 
necessary to build and run the packages within that project.

Is it possible to use the guix.scm or manifest.scm file when 
generating the channels.scm file so it only includes the necessary 
channels? Would I need to create a temporary project profile first 
and then use that to filter the channel list?
