>tests: Fork and exec a new Guile for the marionette REPL....By merely forking PID 1, details from PID 1 (shepherd) would leak into the marionette process, such as the set of modules in scope and state inherited from the shepherd process (<service> instances, fibers, etc.). Running a fresh Guile instance avoids that. * gnu/tests.scm (marionette-program): New procedure. (marionette-shepherd-service): Change 'start' to use 'make-forkexec-constructor', and run the result of 'marionette-program'. Ludovic Courtès
