Chef-client version

[12.x]

Platform Details

[Any supported]

Scenario:

Stray /etc/chef/validation.pem files break Automate install-runner

Steps to Reproduce:

1. Leave an /etc/chef/validation.pem hanging around on a system that will be bootstrapped with automate-ctl install-runner with any current Automate version
2. Attempt the automate-ctl install-runner
3. The bootstrap step of the automate-ctl install-runner will fail
4. Remove the validation.pem
5. Try another automate-ctl install-runner and it should succeed with no other changes

Expected Result:

runner can be bootstrapped

Actual Result:

Runner automate-ctl install-runner bootstrap step fails, because the chef-client running as a part of the command is inadvertently using the /etc/chef/validation.pem that it finds as part of its regular search pattern, rather than a validatorless bootstrap as it is currently designed.
