Distributions like Debian 8 ship a `gpg` (1.4.x) and a `gpg2` (2.1.x) binary, which both use the same config files, and thus cannot be used at the same time, due to incompatible options. Thus we allow the user to specify which gpg binary they want to use.
Scripts
get-coreos
Run the get-coreos script to download CoreOS images, verify them, and move them into examples/assets.
./scripts/get-coreos
./scripts/get-coreos channel version
This will create:

libvirt
Create libvirt VM nodes which are configured to boot from the network. The scripts/libvirt script will create virtual machines on the metal0 or docker0 bridge with known hardware attributes (e.g. UUID, MAC address).
$ sudo ./scripts/libvirt
USAGE: libvirt <command>
Commands:
create-docker create libvirt nodes on the docker0 bridge
create-rkt create libvirt nodes on a rkt CNI metal0 bridge
create-uefi create UEFI libvirt nodes on the rkt CNI metal0 bridge
start start the libvirt nodes
reboot reboot the libvirt nodes
shutdown shutdown the libvirt nodes
poweroff poweroff the libvirt nodes
destroy destroy the libvirt nodes
