+Hi! This is my super-fancy test script that I use for working on the dracut
+module in anaconda. It was never intended for public release so I don't really
+care that it's ugly and kind of stupid in places. It gets the job done and
+that's good enough for me.
+
+If you're reading this, I hope maybe some of this will be useful to you?
