GUIX_PACKAGE_PATH is the deprecated way to use a channel (introduced before tge 
notion of channels). If you have a working dehinition with it, you can simply 
do "git init" and push it as a new repo somewhere. Then, set up your 
~/.config/guix/channels.scm to use it.

To test changes in your channel you can use "-L path/to/channel/root" (same as 
what you pass to GUIX_PACKAGE_PATH) with any guix command.
