how to test service changes

[Martin Becze]

Hi Guix,

I was in the processes of updating geoclue but I ran into a problem. I 
don't know how to test the updated package on my system. geoclue is 
installed by (geoclue-service) in my config.scm. How would I  go about 
making `guix system reconfigure ./config.scm` use my updated package? Or 
is there another way to replace the current geoclue with the newer one?

Thanks!
