Description of problem:

It appears that if the rpcbind service (or other services for that matter, more on that in a second) is already enabled on an F18 system then the AIO install fails. The reason being that "chkconfig rpcbind on" redirects to systemctl with returns an error code becaus ethe link is already present?

If I disable rpcbind and re-run I just get an error on the next service:
