Expanding Bash arrays safely with set -u

Prior to Bash 4.4 set -u treated empty arrays as "unset", and terminates the process. There are a number of possible workarounds using array parameter expansion, however almost all of them fail in certain Bash versions.

Not the perfect idea, but should alleviate the need to resign every cert.

What you need from existing puppet ssl directory:
ca/ca_crt.pem
ca/ca_key.pem

Create an openssl.cnf:
[ca]
