Hi,
I am using buckminster to generate a p2 site for 2 EMF projects. My question, does buckminster (or another tool you know
of maybe?) support merging the generated p2 site with an existing update site?

How does the Buckminster build process do it? (if it does can you point me to some specific parts of the build script to
check out)

Did you look at the b3 aggregator? It aggregates and mirrors p2
repositories, and you have multiple options on how to compose the
aggregation (merge, compose, mirror), and lots more.

And it runs headless too.

If your intention is to really merge the repositories (i.e. to have only
one set of content.jar, artifacts.jar and corresponding features and
plugins subdirectories) then the b3 aggregator is the way to go.

On the other hand if your intention is to create a composite repository
then you may want to leverage the <p2.composite.repository> ant task to
manage the composite repository. This is what we use in the EMF Core
build promotion script
( http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.emf/org .eclipse.emf/releng/org.eclipse.emf.releng.buckminster/promo ter.ant?root=Modeling_Project&view=markup).

Please note that the ant task is provided by the
org.eclipse.equinox.p2.repository.tools bundle which is not a standard
part of any buckminster feature so you'll need to mention it as one of
the IUs to install when installing Buckminster using p2 director.

Here are some pointers to p2 ant tasks documentation:
