Just core-admin-client is not enough. Tests shows that at least:

* GUI domain

* AudioVM

Those two require packaging qubes-gui-daemon component (which includes also audio backend).

* Management VM (including installing templates via qvm-template from there)

This requires packaging https://github.com/QubesOS/qubes-rpm-oxide/ (for the rpmcanon tool)
