[illumos-Developer] zones design question - common door service in all zones?

[Gordon Ross]

I would like to build a user-level door service that runs only in
the global zone (needs to be one instance system-wide) but
which instantiates a service door in every zone.

It would be simplest for this service if it could some how just
expose the same door descriptor attached to multiple files,
one in var/run in each zone.  Or separate doors per zone
would be OK but then this service would need to find out
when tocreate/destroy those doors...

Another thought is to give this service an in-kernel component,
and let that somehow expose the service in all zones.

Ideas?

Thanks,
Gordon
