Plus it's still likely that package names differ.
This is another issue, which I don't think that package manager abstraction solves.
But it is easy to solve by adding name mapping within current host-deploy implementation.
I still think some
abstraction here could help. Try some autodetection on package managers
and prefer packagekit, then try yum, then apt-get, then aptitude for
example.
It is not that easy... we currently use the yum api to be able to participate in yum
transaction, we also require to manage the version lock legacy hack and we need to know
before installation if we can revert to previous version.
So it is not that simple to use abstraction, well, until our product will behave better,
for example it will support previous database schema so that no need to run setup for
upgrade and mess up with packaging.
For now, I truly think that it is easier to just execute apt-get or any other tool, otopi
already built under that assumption.

As a Gentoo user, I don't find this suprising. The whole concept of
USE-flags looks hard to abstract away and still be compatible with all
the other distributions. Especially if there's USE-dependencies in the
mix.
