All too true.

The primary goal of pkgng is to provide a state of the art binary
package management system allowing users to maintain a coherent and
consistent set of packages over time.

Yes, the focus has primarily been on how to upgrade to the latest
available packages, because that's the vast majority of what routine
package maintenance entails.  However, it's not the whole story.  We've
got the ability to 'hold' specific packages coming in release 1.1,
on-going work on the package solver to be able to find an arbitrary set
of packages out of what is available that fulfils specific requirements
(eg. that libreoffice version x.y.z is installed, together with the most
up to date possible version of firefox consistent with that) and with
all the package dependencies met, plus I'm thinking about a feature for
having an 'undo' capability.  Much of that can involve installing or
leaving in place older versions of packages.

	Cheers,
