Outright wrong, as has already been explained in this thread several times. > 2) If a package manager leaves two versions of a non-slotted package > "installed" somehow, that package manager is fundamentally broken and > its author should forever refrain from specifying anything.

The install sequence is carefully designed to install the new version of the package, and then remove the old one (and if you think about it for a few seconds, you can see that it *has* to be this way). If an error or ctrl+c occurs at the wrong point, both versions remain installed, and importantly, there is a safe way to recover from this. -- Ciaran McCreesh
