gnu/services/base.scm do not import `(gnu services 
configuration)`.  IMHO,
`define-configuration` is good for serializing record-like 
configuration
to custom formats.  Here we actually need and configure executable
programs.  I was not the one who introduced them, but currently I 
find
them more useful here.
