Subject: [PATCH 2/5] guix home: import: Allow multiple modules to be
 imported for each service.
Date: Tue, 28 Sep 2021 19:35:47 +0200

Previously, only one module could be imported for each service, e.g., only
(gnu home-services shell) could be imported when generating the Bash service
declaration.  However, for some services, multiple modules might need to be
imported in order for it to work.

* guix/scripts/home/import.scm (generate-bash-module+configuration): Rename to
...
(generate-bash-configuration+modules): ... this.
(%files-configurations-alist): Rename to ...
(%files+configurations-alist): ... this.
(modules+configurations): Rename to ...
(configurations+modules): ... this.
(manifest->code): Adjust accordingly.
