Seems sane I guess.

Right, I think yum wants to do something similar in the future.

I think this spec is already used in PackageKit, let me explain why:
user: Install abiword
application: GetDepends(abiword, ~installed)
PK: abiword-libs, expat
application: "To install abiword, you have to install abiword-libs and
user: clicks okay
PK: installs abiword, and automatically downloads and installs
abiword-libs and expat
So only the key application (what the user wants) is passed to
InstallPackages. This is the one you would add to the world list. The
other deps would just be downloaded, built and installed, without
being added to the world list. The other deps don't get passed to
Does this make sense?
