One of the things the autorelease build scripts does is calls a `rsync` to prep the staging repo. For deployment

It would be more efficient if we follow the build strategy employed by the maven-release job which does not need the rsync step. This would cut down about 1/3rd of the disk size needed to run autorelease builds most likely.
