If you have a dash "-" in the persistent-id then if you override the
properties file in $FUSE_HOME/etc with the name <pid>.cfg then it
won't
pick the property file up.
so stuff-test.cfg will not work so change to persistent-id="stuff.test"
and
call the override file stuff.test.cfg will work fine.
Hope it saves you some time.
