Few patches to make life on Debian 6 stable happier:

 * Added arguments to packages/bddeb:
   -d pass through '-d' to debuild
   --no-cloud-utils don't depend on cloud-utils package (default: False)
 
   These are essential for building on Debian 6, because there are
   no python-mocker (build dependency) and cloud-utils (install dependency)
   in squeeze and squeeze-backports.
 
 * SysVinit startup scripts modified to run both on RHEL and Debian,
 * (Unfortunately) New option INIT_SYSTEM=sysvinit_deb for Debian /etc/init.d/ 
   directory
 * Make separate Ubuntu and Debian APT source template (cc_apt_configure)

I'm now generating working Debian 6 package following way:
INIT_SYSTEM=sysvinit_deb packages/bddeb -us -uc --no-cloud-utils -d
