Yes, I wasn't clear but I meant *Shepherd* needs a proper logging
infrastructure (although it seems to me the logging library in Guile-Lib
could be used in any Guile project, Guix included -- the way the
'logging' module comes standard in Python and preferred to printing or
reinventing a logging system :-)).
