Initial setup for maru debian for nexus 5.

We do this separately because it's constrained for space much more than
any other host. The maru debian takes up about 1.5G. We start with about
6.8G free. We want to keep a few gigs free to take pictures and
movies. I should really trade this in for a 32GB version.

-h|--help  Print help and exit.
