When you do “guix package -i” it will use the current version of Guix to
create a new profile generation containing all of the previously
installed packages as well as “guile-json”.

Neither of these commands know about your manifest.  Your manifest could
be located anywhere.  Only “-m manifest.scm” instantiates the manifest
in the provided file.
