`sudo ./flashEMMC.sh [block device name, e.g. sdb]`

This script automates the installation of the ArchLinuxARM ODROID C2 image. (as shown on the [ALARM installation page](https://archlinuxarm.org/platforms/armv8/amlogic/odroid-c2#installation))

It shows the user information about the block device they indicated, asking if it is the right device. If it is, all mounts related to this block device are unmounted, a couple of blocks at the start are zero-ed out, the partition table is created, the single partition's FS is created, the ALARM image downloaded, hash verified, the parition is mounted, the tarball extracted, then the bootloader is installed. Finally, everything is `sync`-ed, and the directory unmounted.

### ansible.sh

Usage: 

`sudo ./ansible.sh [playbook file, if none, site.yml]`

It simply verifies that the ansible requirements.txt are met and runs through the specific playbook.
