Code

guix home: import: Make the user to specify a destination directory. 

Copy the appropriate the relevant configuration files to the destination
directory, and call ‘local-file’ on them.

Without this, ‘guix home import’ will generate a service declaration like this

  (service
   home-bash-service-type
   (home-bash-configuration
    (bashrc
     (list (slurp-file-gexp
            (local-file "/home/yoctocell/.bashrc"))))))

but when running ‘guix home reconfigure’, the ~/.bashrc file would be moved, so
when running ‘guix home reconfigure’ for the second time, it would read the
~/.bashrc which is itself a symlink to a file the store.

* guix/scripts/home/import.scm (generate-bash-module+configuration): Take
‘destination-directory’ parameter
(modules+configurations): Copy the user’s configuration file to
‘%destination-directory’.
* guix/scripts/home.scm (process-command): Adjust accordingly; create
‘destination’ if it doesn’t exist.
