Don't forget that obsolete packages are not auto-deinstalled. They are
only marked as being obsolete.  It is up to the user to uninstall them.

Why would anything be marked for removal?  The only time things are
auto-removed is if nothing else depends on them any more (and if they
were originally auto-installed).

The only time I would suggest making it so you couldn't install a
package is if all the "Depends on" (as per the header) packages are not
available or being kept back to previous versions.  And then I would
also include an override.

I don't understand when your example would occur.

I don't know how agressive deity is really.  In all cases deity should
be making informed choices and then letting the user review all those
choices before proceeding.

Something like that.  I was thinking of moving a good "inst" button into
the status box, but anything like this will do, as long as it is a tiny
bit of a pain so people don't get in the habit of forcing things.

Fair enough.
