* Changed config to point to my github fork and ran the builder script to create packages.
* Installed daemon and startup scripts rpm on CentOS and verified it succeeded and files were updated correctly.
* Installed daemon and startup scripts deb on Debian and verified it succeeded and files were updated correctly.

* Created new image with CentOS and Debian using gcimagebundle.
* Uploaded image files to BigStore and created test images.
* Created CentOS and Debian instances with test images and startup scripts.
* Verified startup script output and that instances contained updated scripts.
