## Stacktrace
<!--- Please include the stacktrace.out output or link to a gist of it, if there is one. -->

Start with the AIX path exercised by the supplied knife bootstrap command and the referenced install.sh flow; verify how the 15.8.23 package is installed when AIX reports chef as already installed. The report names no repository file or test, so done means reproducing the failure and confirming that a bootstrapped AIX node can invoke chef-client.
