     To be clear, let's concentrate on the part of init which is the 
concern: the daemon-launcher.


     I don't think things are as complex as is suggested by the comments 
I have read up to now.


     There are two categories of launchers: supervisors and 
non-supervisors. Similarly, I think two scripts only are needed for 
every daemon: one for launching without supervision, alla sysv-init and 
one for launching from a supervisor. Just two, not one per every 
launcher/supervisor.


      Further more, a method could be agreed on to tell the script if 
the daemon is going to be supervised or not, and we would then need only 
one script for all cases.


     For example, providing "supervised-start" and "supervised-reload" 
in addition to the other cases could do the job. For safety, the scripts 
could check a file which tells them which supervisor is calling them.


     What do you think?
