Starting the interpreted (node.js, python etc.) services are often way more complicated than what is described in handbook but I always spend about 30% of time by doing the start part and 70% of doing the part required to stop the service - matching command / interpreter / procname is not an easy task and debugging it is even more complicated. Almost always one need to tune just these 3 variables command, command_interpreter, procname but it is sometimes too difficult if one do not have deep knowledge of how things works in rc.subr and sometimes even reading the source of rc.subr is not clear to me.

I'm afraid there is nothing else.

Regarding the services running interpreted programs, I agree that the interface could be a bit more friendly.
