What is an `immediate configure' package ?  No Essential package may
depend on anything that isn't Required.  (I don't know if this is
stated anywhere, but it clearly should be.)

This will be satisfied by all Essential packages' dependencies being
Required.  Clearly Required will be on the first CD if we split by
Priority.

What is a Conflicts/conflicts loop ?  Is that what you discussed on
debian-devel when I said to deconfigure or deinstall the relevant
package(s) ?
