Whereas the deployment-scanner is a single client for standalone, which
is under our control. So i wanted to see if we there is a way we can
make this work which also satisfies your use cases.
I have two things in mind which i'll try to explain quickly:
1) you still link the overlays as part of the <deployment />, however
the deploment-scanner is aware of that and won't remove deployments with
overlays until you use a specific invalidation marker.
</pre></blockquote><pre wrap="">This requires that the overlays be controlled by the scanner as well.
Why? Because we don't persist the model resource for scanner-controlled
deployments. So if a user linked a non-scanner-controlled overlay to a
scanner controlled deployment (which seems quite rational if the overlay
involves some environmental settings that never change), the link
information will be lost on server reboot.
</pre></blockquote><pre wrap="">I know, but that's an ancient limitation. I guess we could just start to
persist stuff.
</pre></blockquote><pre wrap=""><!---->
We'd have to persist some association between a deployment and a scanner
(e.g. scanner="default" on the deployment element) and then use that to
indicate that the server should not auto-deploy on boot but should defer
to the scanner to tell it what to do. And then alter the scanner to add
logic for it to reconcile the state it sees in the scan directory vs
what the model shows.
Doable, but a fair bit of work.
I considered this before going with the "don't persist" approach. I
don't recall though if there was some fundamental problem with it that
I'm not remembering, or if it was solely that "don't persist" was doable
within the time constraints.
</pre><blockquote type="cite"><blockquote type="cite"><blockquote
type="cite"><pre wrap="">2) use overlay directories - this is more the file based approach, Where
we just pick the "deployment.name + suffix" for the overlay. So there
would be an automatic overlay/linking done by the deployment-scanner.

</pre></blockquote><pre wrap="">Not really. It can automatically recreate the overlays therefore it does

It can only recreate the association for overlays that it scans, not
ones that were added via CLI/console.

fundamentally differ from what Stuart proposes in terms of how to
organize the data?
</pre></blockquote><pre wrap="">Well that is the point. It's basically the same, just that it removes
the requirement for the additional linking in the domain.

Another idea I had is that we could do something like define the overlays at domain level, but then define the links at server group or server level using the same name. basically something like:
/deployment-overlay=myOverlay/content=WEB-INF/web.xml
/deployment-overlay=myOverlay/content=WEB-INF/ejb-jar.xml
/server-group=server-group1/deployment-overlay=myOverlay/deployment=test.war
/server-group=server-group1/deployment-overlay=myOverlay/deployment=*.war
For standalone they would just be combined, similar to what I had below:
/deployment-overlay=myOverlay/content=WEB-INF/web.xml
/deployment-overlay=myOverlay/content=WEB-INF/ejb-jar.xml
/deployment-overlay=myOverlay/deployment=test.war
/deployment-overlay=myOverlay/deployment=*.war

Having overlays as part of the deployment means the lifecycle is managed together, so the deployment-scanner could define it's own invalidation policy. May it be based on whether the content got removed or we have a specific marker for that.
We could also think of providing a file-based overlay solution, managed by the deployment scanner only. In the end people use the deployment-scanner for a reason, so perhaps not having to worry about the model or "content" folder could be interesting. This would not even need to access persistent information though. Anyway just some ideas on the side.
</pre><blockquote type="cite"><pre wrap="">It also has to be specified on every re-deploy.
</pre></blockquote><pre wrap="">When you do a "remove" and "add" then yes. We do have specific operations to replace the content and redeploy the deployment without removing the information from the model.

is to just move the links under the deployment-overlays element and loose the
flexibility to link at different levels. e.g:
