Hello,

I am going to start with the second patch, because that is going to be shorter :)

Although this has been like this before, I am strongly against passing anything from the request to the setuid binary.

This will open us up for any shell command injections and so on. I would prefer to check the second argument to be at least on some kind of list as there are only a few keywords allowed (start, stop, restart, …) and the other parameters should only contain ASCII letters, numbers and maybe dash and underscore. Nothing else should be passed through here.
