[galaxy-dev] job_conf.xml and nativespecification

Hi galaxy users, while using galaxy with drmaa and real user on drm system, I would like to know if there's a way to set the variable PBS_O_LOGNAME to the real user name in the job_conf.xml : <param id="nativeSpecification">-v PBS_O_LOGNAME=[REAL_USER_NAME??] -q test -l mem=100gb </param> Thank you, Laure
