Subject: Heads-up: solaris10 branded zones

The putback of:

PSARC/2009/253 S10C
6666646 Solaris 10 zones on OpenSolaris binary (supported) distributions

introduces a new type of branded zone which is capable of running
Solaris 10u8 (or later) on OpenSolaris.

This brand has a potential impact on any future code change which crosses the
user/kernel boundary in either Nevada or S10.  Now that this brand has
integrated, it is the responsibility of the development community to ensure
your changes don't break the brand and to fix any brand-related bugs created
by your projects or bugfixes.

We'll be holding a KTD and various TOIs to communicate more details about
working with this brand.  We have also written a developer guide which
discusses the issues developers need to be aware of when making changes
across the user/kernel boundary, as well as how to test that your changes
don't break these branded zones.  The guide is available at:

http://www.opensolaris.org/os/community/zones/s10brand_dev_guide/

This is a living document, so we would appreciate any feedback on
improving the guide.

Anyone in the community making a source contribution which crosses the
user/kernel boundary, along with the the person sponsoring the change,
should also be familiar with the issues discussed in the developer guide.

We'll be happy answer any questions on zones-discuss at opensolaris dot org.

Brand-specific bugs may be filed under solaris/brandz/s10_brand.
