I view it as something more generic: it=E2=80=99s typically, but not just, = for when the service comes from a procedure defined in the Shepherd itself. Other use case is when as a service author you need more freedom that what you get with the =E2=80=98start=E2=80=99 and =E2=80=98stop=E2=80=99 fi= elds, like: (shepherd-service ;; =E2=80=A6 (free-from #~(let ((whatever (spawn-fiber =E2=80=A6))) (service '(foo) #:start =E2=80=A6)))) It=E2=80=99s probably going to be a relatively marginal use case, but it=E2= =80=99s good to have that extra level of flexibility. WDYT? Thanks! Ludo=E2=80=99.
