Samba and AIX SRC support

[David Collier-Brown]

   Note that this is similar to the Solaris service management facility
(smf), which does the error detection and dependency handling
for everything that used to live in rcN.d directories.
   You might want to look at the AIX, Solaris and rcN.d systems
and decide if there is a common subset or superset...

The former is probably a better solution, since an application could be multiple processes that the deamon might not know about. Having said that, the force stop is probably a redundant functionality, since most rc script 'stop' functions are pretty forceful to start with :)
