That's not true: we're doing as if the people only have basesystem-minimal + X 
+ rpmdrake + the package being updated and all its dependencies, recursively. 
Except in case of a bug in our script, the listed packages are not present in 
such a system before the update, and are required from Release media for the 
update.

If we were doing as if people were installing from scratch, the list would be 
the output of urpmq --requires-recursive, just test and check that there's a 
really huge difference :)

Either there's a bug in our script, or kdebase4-workspace-devel in Core 
Release didn't require any of those packages, directly or via its 
dependencies. 

Now, we probably can find lots of cases where there's a "high" chance that some 
of the listed packages are already present on the user system, and those can 
be discussed. But the QA team already put hours and hours of work trying to 
workaround bug #2317 so I hope it's not a big deal if we link a few packages 
more than what is really needed for most users. Trying to be more precise (and 
we already are quite precise) would just make us go insane (and next step we'd 
all stop validating packages to go learn perl and rpmdrake internals in order 
to change MageiaUpdate's behaviour).

They weren't required according to urpmq --requires-recursive, but there's a 
limitation in urpmq --requires-recursive when there are alternatives : if 
package A requires B or C, then urpmq won't list the dependencies of B and C 
recursively. Some call that a bug, I prefer to call that a "how the hell could 
we do differently?" feature :)
