The attached patch does both and works :-) Tested by having grub-installer apt-install both grub and anacron (the latter is on CD2).

The patch does introduce an inconsistency that will need to be resolved: with multiple CDs in sources.list package installation will be interactive (including any configuration questions) while in other cases the installation will be non-interactive.

What's the reason we made apt-install non-interactive? Was it just that we did not have the passthrough frontend at the time? If so, I guess we should probably just make apt-install interactive in all cases.
