To blow the fire bottle(s) for a hot start seems a little excessive, but maybe they actually had fire lights also and other indications. As for the 717 being a new name for the MD 80, yes and no. The 717 is/was a McDonnel product that was a complete remake of the MD80/DC9 series that boeing decided to continue producing, at least to satisfy the initial order backlog. New engines and at least two versions, stretched and what not. They were going to close the line, but I think orders have been enough to keep it open. Don't quote me on any of that.
