Azure Red Hat – RHUI Update

Most of the this script is based on the document “Red Hat Update Infrastructure (RHUI) for on-demand Red Hat Enterprise Linux VMs in Azure” at https://docs.microsoft.com/en-us/azure/virtual-machines/virtual-machines-linux-update-infrastructure-redhat?toc=%2fazure%2fvirtual-machines%2flinux%2ftoc.json

My change will first check if the update was already installed, if not it will follow the process to install

See updates at: https://gitlab.com/Kittell-RedHat/AzureRepo/raw/master/AzureRedHatRepoUpdate.sh

#!/bin/sh

#  AzureRedHatRepoUpdate.sh
#
#  This will update Azure Red Hat servers to the new RHUI Repo if needed.
