And you draw this conclusion because?

Which law of nature prohibits updating the desktop in an update
release?

When the desktop relies on other components that rely on other components that rely on new kernel bits that can't for some reason be backported. Even if they could, by this stage you've almost got a traditionally non-update release? Technically possible, may even socially acceptable, but requires a hell of a lot of coordination ;)


Yes, it does ;-)  As Casper pointed out, we are doing this
right now to get Trusted Extensions out, and there have been
other projects in the past that had "cross-consolidation" dependancies.

We do, as a matter of course, have to limit which features can
come into an update release.  We normally start with a list of
features that will be ready in the correct time frame that are
interested in backporting, then we get marketing to do a first
pass to determine  which features would actually be desired or
used by S10 Customers.

Obviously, some things, like ZFS, were originally marketed as
an S10 feature, but did not quite make the release.  Those things
are utmoust priority to get out in an update.

Within Sun's software developement, we use something called "binding"
determined by our architectural review committees to help determine
the appropriate releases such a change can target.  Nevada (OpenSolaris/S11)
is micro binding right now - so bigger changes can go in there that
cannot go into an update (which are "patch" binding, since the updates
are essentially made up of patches).  It's all based on interface
changes & ability to backout or not use a feature.
