Description Andrew Niefer CLA 2009-07-10 15:16:58 EDT 
+++ This bug was initially created as a clone of Bug #283091 +++

Build performs a mirror or the product being built from context + build.repo into build.repo to ensure all requirements are present for the call to the director.

This is currently done with the slicer set to treat everything as greedy.

A feature based product will require the IU
'tooling.org.eclipse.update.feature.default' which has a requirement
<required namespace='org.eclipse.equinox.p2.eclipse.type' 
          name='feature' range='0.0.0'
          optional='true' multiple='true' greedy='false'/>

This will be satisfied by every feature present in the context repository, and will result in nearly the entire context repository being mirrored into the build repo.

This is potentially a huge performance problem.

Build should instead perform this mirroring without following non-greedy things.
