- Have the buid system generate a file which exports the install paths for the hotplug scripts and stubdom / stubdom-dm - Move file generation code from tools/python/Makefile into a gmake macro in Config.mk to avoid maintenance of three duplicates each with its own tweaks and bugs - Export gmake variables into ioemu as shell variables for upcoming ioemu patches - Do above as a gmake macro to avoid maintenance of several duplicates - Adjust hotplug scripts to find the right xen binaries from the install directory - Adjust stubdom-dm to use the install directories Signed-off-by: Christoph Egger <Christoph.Egger@amd.com>
