 ## Special note when remote target is on the same host as initiator (happens for unit tests): we'll have to differentiate RUN_DIR so remote CleanUp won't affect initiator.
+## If the same program gets remotely executed, add _REMOTE_EXECUTION=true to it's environment so it knows it has to write into a separate directory
+## This will thus not affect local $RUN_DIR variables
