No, because base-config installs the ubuntu-desktop task, not the
ubuntu-desktop package. (We keep the two in sync.)

I would recommend not modifying the ubuntu-desktop package, because that
will create upgrade issues if somebody wants to upgrade from one of your
CDs to plain Ubuntu. Just have base-config install the extra packages
you want.

Not in our installation; we have a tool called germinate that works out
what should be on the CD, and we disable debian-cd's

That depends what you mean. debootstrap doesn't, but you didn't seem to
be talking about that.

That's one way, but if you're rebuilding the CD anyway then just put
them in the local tree and let debian-cd take care of that.
