The role will just wipe away the machine and install a blank image.

To secure your machines from being wiped out accidentally, ansible should create a hostcode file (etc/hostcode) with an md5 string from the hostname.

Before starting to wipe out the machine, ansible needs to enter the machine with the host-key and check for /etc/hostcode being not available.
If the machine could not be accessed, ansible can be configured to interpret this as an indicator for the machine to be virgin (and therefor deployable) or an allready production system and therefor be untouched.

Since an "UNREACHABLE" Error can not be handled by ansible (and meta seems not to work), we check the connction to the server with pubkey-key and user root first by a local ssh action.
