With the auto installer present, the crucial question is how we get the
answer file. This script implements the way of a local disk/partition
present, labelled 'proxmoxinst', lower or upper case, with the
'answer.toml' file in the root directory.
We either want to use it directly and call it from 'unconfigured.sh' or
see it as a first approach to showcase how it could be done.
