SUNWxim does not depend on SUNWdtdte. Therefore, a patch for SUNWxim,

business pulling in an implied dependancy on SUNWdtdte either.
But it does, and the patch fails without it.
That fairly tightly fits my own personal definition of
"broken patch creation policies/procedures".
So, how is switching to the "better technology" of IPS, going to
solve this
problem of broken patch creation process inside of Sun?
Hey Phil: Very easy! As no "--no-deps" is "supported", your scenario
would not even be possible anymore, not at all. That's the solution
(really).

But that is still inadequate.
Sometimes, there are VALID patch dependancies. Sometimes, you really do NEED
dependancies updated, when you update/patch one package, otherwise, the
patch breaks things.
If "[pkg update]" is taking the place of "patchadd", then there should be a
mode to pkg for, "install/update everything that is installed, but dont add
anything NEW".
Otherwise, the --no-deps is inadequate.
Philip - the answer is relatively easy - as there are no patches in IPS.
Not exactly true. there will still be patches, effectively speaking. you're
just not allowed to CALL them "patches" any more. they're just called
"updates" or whatever.. but there still needs to be the same QA done as when
you release a "patch", in terms of, "what does this change affect, what are
the side effects, what else needs to be updated?"
And if sun doesnt improve the way they are handling patches right now, there
will eventually be the exact type of problem I described in my original email:
Sun engineers will release a new "[patch/version/update]" of something, for
bugfix purposes. But if they dont properly scope the update, it will either
FAIL on deployment (because some truely required dependancy was not updated
as needed), or it will pull in junk that isnt really needed on the system.
