Preliminary Debian support

This is based the work in #6 by @saz.

Added a new init.d file for Debian, which requires the "daemon" package.
This will be automatically required on Debian systems.
There's not a commonly used module that 'owns' this package?  If not, this should be an `ensure_packages()` declaration or removed.  Also, there's no dependency ordering declared.  I assume this package would need to be present before any service resources run?
