IIRC the it was the field exerciser that did that by default. I seem to remember that you could configure it to use something else like the field service pack itself or may be not disk at all, but if I remember right if the exerciser found an RS04 it thought it was available by default. So, I had a big sticker on the FS pack that said see me before you loaded it after the first time the service guys took out /tmp. ᐧ -------------- next part -------------- An HTML attachment was scrubbed...
