Patching RHEL 7 VMware Template using Satellite

Hello,

I have an idea of how I want to do this, but I would like to make sure i'm not off to left field so to speak?

My situation: We have a disconnected web server that we use as a repo server. We export repos from CDN and import the content there. Our RHEL 7 VM templates are config'd to point to the web server to get yum content.

Moving forward we are deploying Satellite to essentially replace the repo server so we can start leveraging features within Satellite. To start, we want to use Satellite to patch our RHEL boxes. Later we want to look at day to day configuration mgmt tasks to support our boxes.

Anyways, we have a RHEL 7 VMware template (Side info; not sure if this is important: I have a local RHEL 7 ISO and Satellite Tools ISO I exported from Satellite mounted as local yum repos on my template so I can install the katello-agent and have RHEL7 packages available) that we want to keep up to date. Since we will not have the web server anymore, my thought was to install the katello-agent onto the template, register/subscribe it, and update it accordingly. I testing this out and it worked great.

Now that the template has been patched, I need to clean it up so i can convert it back to template. What I thought I would do is keep katello-agent installed but I would unregister the template from Satellite. So I think I would need to run the following before shutting it down:

subscription-manager unsubscribe-all
subscription-manager unregister
subscription-manager clean

So now I shutdown the server and convert it to template. When I deploy (clone it) the machine, it will have a new server name and IP, like it should. At this point, I think all I need to do is subscription-manager register --org "org name here", and provide creds, OR enable auto-attach/subscribe??

Moving forward, when I need to patch the template, I turn it on, register, patch, unregister, turn off.

Would this be a good plan, or am I out to lunch?
