This makes a bunch of variable cleanups that will let -o nounset function, for the time being we hide nounset behind another setting variable so that it's not on by default. Because this is bash, and things are only executed on demand, this probably only works in the config it was run in. Expect cleaning up all the paths to be something that takes quite a while. This also includes a new set of unit tests around the trueorfalse function, because my change in how it worked, didn't. Tests are good m'kay. Change-Id: I71a896623ea9e1f042a73dc0678ce85acf0dc87d
