This is so that the options supported by the service configuration don't have to always be changed. Generally though all options should be explicitly supported and documented, so this is mostly to facilitate experimentation. * gnu/services/cuirass.scm (<cuirass-configuration>): Add an extra-options field. (cuirass-shepherd-service): Pass the extra options to the shepherd servvices. * doc/guix.texi (Continuous Integration): Document it.
