Even the fact that ./crwctl/bin must be in the $PATH the installation script is not able to manage probably hardcoded paths to its resources/templates. When the installation is executed out of the crwctl folder, then it fails. It should process correctly and use resources from the path which is on the correct folder relatively from the crwctl binary.

~ root(ocp:default) $ crwctl server:start --installer=operator -n codeready --self-signed-cert
