    reproducible debian: vary HOME between builds
    
    This is done by setting the BUILD_HOME pbuilder conf value in the temporary
    pbuilderrc, which is then used by pbuilder to set HOME.
    
    Remember that those home directories don't actually exist, as build processes
    are not supposed to write to HOME nor rely on that.
