Hmm, I would have thought that you would want the configurationManager

I don't know. Taking the practical approach, I just tried adding a
second ConfigurationStore to system-plan.xml, and at that point the
server wouldn't start because a couple of components expected a single
ConfigurationStore thart they were provided via GBean references. It
sounds as if you're proposing that each Deployer be configured with a
more specific reference so that there's a 1-1 relationship between
Deployers and ConfigurationStores, whereas I was thinking more along
the lines of a single Deployer that knew about multiple configuration
stores. Your idea sounds fine, but what's the mechanism at runtime
that chooses which deployer to use based on the target?
I'm guess I'm not clear on the relationship between the
configurationManager and the Deployer(s). When I looked at the
backtrace from the Deployer.deploy() method I didn't see the
ConfigurationManager in it. Does the configurationManager have an
opportunity to delegate certain ConfigurationStores to certain
Deployers?
no
The configuration manager is responsible for running the server using
stuff that is available in all the repos and config stores it knows
about. The deployers only need to know where to put the completed
configuration when they are done with it. If they know about more than
one, I don't know how they could decide.
My understanding of what this could be used for is something like a
shared immutable config-store used for "official" configurations and a
non-shared config-store you could put your own stuff into. In this
case, the deployer would point at the non-shared config store. Very
likely we could make the immutable config-store based off the geronimo
repo using packed car files directly. I've forgotten what you
originally wanted this for, could you remind me?
