blech - nevermind. still throws horrible errors when the service has not
been installed yet and puppet runs (such as on a new VM).
Is there any way to have it see that there is an error during the uninstall
and then run an ELSE and move onto the Install portion without getting hung
up on not being able to uninstall first? this is the step I can't seem to
figure out.
