Assuming we are using normal (not supermounted) media, many people are complaining that they cannot eject CD after installing something with urpmi/rpmdrake. The reason is obvious - they (programs) mount CDs but do not umount them. You may be surprised, but the fact that you have to unmount CD to be able to eject it is not widely known (and many users do not even know how to do it anyway).
I suggest to take some conservative approach. If CD was not mounted when urpmi was started - umount it after installation has completed. If CD was already mounted - do not touch it (assume user knows what he's doing). If you have had to change CDs during installation - it looks reasonable to unmount it as well. Comments? -andrej
