uprade from CD leaves cdrom in apt sources.list

[Greg]

Binary package hint: debian-installer

I perform upgrades from the alternate installer CD image. After the upgrade, there is a cdrom entry in /etc/apt/sources.list which can be troublesome when the CD isn't in the drive. I think that the default configuration should be to remove the cdrom entry after the upgrade as I expect most people who use a CD (or mounted iso image) will not leave it in the computer after the upgrade has completed. I upgrade from CD because I have 5 machines to upgrade; this way, I only have to download the upgrade once. This happend on the upgrade to maverick and I expect it would happen when I upgrade to natty.
