in this case, zypper resolves the dependencies and offers to install
pkgA-0.1-1
Why doesn't it suggest now also to install pkgA-0.2-1 together with
libpkgA0-0.2-1? Wouldn't that case be the logical one?
Actually, thats a policy decision, not a dependency decision.
(And one of the reasons we want to make policies configurable in 11.0)
One of the current solver policies is 'minimize the transaction': the
fewer package installs/upgrades/removals the better.
Thats why pkgA-0.1-1 is preferred over pkgA-0.2 + libpkgA.
Klaus,
Thanks for this clarification... Makes sense after reading it. It's just a bit
surprising that it bring s you to a system where, just after installing, you're
offered to update to the latest version, if you check the system. And the
update even works.
