Thanks, I'll do that and see what everyone wants to use it for.


To me, the obvious place for these kind of server-specific ops in domain
mode would be under /host=*/server=*/ probably under sub-model since
there could be a non-trivial number of useful operations. Operations
there get routed to the server to execute, but I need code run on the HC
instead.

I've seen the HOST_CONTROLLER_ONLY flag which sounds like what I want,
but that doesn't affect /host/server ops. Am I mis-understanding the
flag and that's not what it's for, or should it work?

PrepareStepHandler uses isServerOperation() to direct operations under a
server to the instance without regard for HOST_CONTROLLER_ONLY, and
OperationRouting.determineRouting() only checks the flag if it's not in
that location.
