I'd go with maybe 8G at the most. SNV is comfortable in 4-5G today so that should cover any growth of solaris itself. Are the developer tools something that would need to be upgraded in lock step with Solaris? If so I think that's a shame, and might ahve to add to the size of /, but if not then they belong in a separate partition (I'd personally put them in /export/something and share them among all my machines.) Ditto with blastwave. That will update at a much different rate than Solaris, and won't need to change during a LU. Why have 2 copies of it around when 1 could be shared among BE's? Unfortunately the companion stuff (this is where /usr/sfw comes from right?) can't easily be split out that way. This is just another reason why I never install it. How many live upgrades are going to have a new companion DVD that go with them? S10_U[123] didn't I don't think. SNV build X doesn't get a newone. SO only when moving from S10 -> S11 will the companion stuff need to change, and I beleive that is done separately after the solaris upgrade. All good reasons for keeping the stuff from the companion DVD separate enough from the core Solaris Install so that it doesn't complicate LiveUpgrade. I think the goal should be to share as much as we can between BE's. -Kyle > And if you're thinking of LU, you probably do want to split out > /export/home > despite the fact that it's otherwise a really bad idea.
