-Welcome to the CoreOS live environment. This system is running completely 
-from memory, making it a good candidate for hardware discovery and 
-installing persistently to disk. Here is an example of running an install 
-to disk via coreos-installer: 
- 
-sudo coreos-installer install /dev/sda \ 
-    --ignition-url https://example.com/example.ign 
- 
-You may configure networking via 'sudo nmcli' or 'sudo nmtui' and have 
-that configuration persist into the installed system by passing the 
-'--copy-network' argument to 'coreos-installer install'. Please run 
-'coreos-installer install --help' for more information on the possible 
-install options.
