OpenSolaris Zones: TX & BrandZ

Trusted Extensions (TX) integrated into OpenSolaris before BrandZ did so TX doesn't use the branded zone zones concept.  BrandZ wasn't just about providing the ability to run userland Linux code in a Zone it also provided an infrastructure to support different styles of zones, it doesn't even need to be some thing as complex as a Linux zone.  There are instructions on the brandz mail alias for creating a Belenix zone hosted on Solaris Express in this cases the branded zone doesn't require a different kernel module.

I think it should be possible to use the BrandZ hooks to avoid the need for doing some of the additional zone creation work that needs to be done manually for TX zones, or via tools like txzonemgr.

Currently lx branded zones (Linux ones) aren't allowed to exist if TX labeling is enabled but that is a different issue than using the BrandZ infrastructure to create TX zones.
