Ty for this change. The core issue is when running a distribution, say docker for example, this script would exit with 1 however the cluster spin-up will continue which will cause admin user to be created since internal_users.yml was not modified by this script to update the new admin password.

Would you want to take a look at identifying and fixing that? It might involve you looking and fixing things outside security repo. Here are some resources to help you get started in case you are interested:

• [Security] Demo configuration script requires admin password  opensearch-build#4094
• Add a warning info and hard stop for security demo setup opensearch-build#4105
