+    For example, if you provision a VM from an RHEL 7.2 PAYG image and run `sudo yum update`, you end up with an RHEL 7.5 VM (the latest minor version in the RHEL7 family).
 
     To avoid this behavior, you need to build your own image as described in the [Create and upload a Red Hat-based virtual machine for Azure](redhat-create-upload-vhd.md?toc=%2fazure%2fvirtual-machines%2flinux%2ftoc.json) article. Then you need to connect it to a different update infrastructure ([directly to Red Hat content delivery servers](https://access.redhat.com/solutions/253273) or a [Red Hat Satellite server](https://access.redhat.com/products/red-hat-satellite)).
