Hi cdelia,

When you do =E2=80=9Cguix package -i=E2=80=9D it will use the current versi=
on of Guix to
create a new profile generation containing all of the previously
installed packages as well as =E2=80=9Cguile-json=E2=80=9D.

> It will honor the manifest or just install the guile-json on the package

Neither of these commands know about your manifest.  Your manifest could
be located anywhere.  Only =E2=80=9C-m manifest.scm=E2=80=9D instantiates t=
he manifest
in the provided file.
