No, not really.  The Samba suit has a lot of tools that may want to look
into the default config directory.  It seems that any relevant
configuration belonging to Samba lands in smb.conf, that is looked into
anytime when needed.  That is my impression, and thus
placed it there.

I'm not so sure myself.  That was the end result of what had to be
created to have the service successfully initiate itself.  True that I
have not investigated this myself yet.  While writing this service I was
comparing the directory structure with Debian and Arch Linux, to be sure
that it would work.

My understanding now would be better to write invoke.  Thanks for
pointing this out.
