Update an existing production server

All production servers contain files used to provision the server with updates. These files should be run in order.

1. prep.sh prepares the server with the latest files from the WSU Web Provisioner repository.
2. bootstrap.sh updates Salt using the latest version of Salt’s bootstrap script.
3. salt.sh runs the provisioner.

The salt.sh script will often take the longest. Watch for the number of passed and failed commands after Salt has finished to determine if further action is necessary. If all commands have passed, then verify all crucial services and sites on the server are running as expected.
