Re: [p2-dev] can platform be updated via p2?

OSGi frameworks allow installing several versions of the same bundle, unless they are marked as singletons.  If you want to replace a bundle or feature, you need to first remove the old and then install the new.

That's because p2 looked for a version that would satisfy all the other IUs currently installed — including org.eclipse.platform.ide 3.6.0.  Since 3.6.1 would cause an error with 3.6.0, it chose to re-install 3.6.0.

You should get more mileage by using "-uninstallIU org.eclipse.platform.ide -installIU org.eclipse.platform.ide".  You can also force a particular version with 'org.eclipse.platform.ide/3.6.1.r361_v20100909-9gF78GrkFqw7GrsZnvz0JWNTeb6fue6896L', though I think you need to specify the full version
