Adding help and checks to the new ubuntu init and cosmetic fixes:

* Extended the if statement checking for the new config to alert if no default config exist, before starting with defaults.
* The new defaults file setup changes the variable names and they can confuse some, added comments to clarify.
* Added cosmetic changes to the comments so capitalization is now the same everywhere and cleaned up indentation so they are the same
