Dear Urs, What I obtained is below. Unfortunately, a bit mobile now, I have only the USB stick to work on SL6 and so cannot un-install it as such; but I had no complaints!
I recall when installing SL6 on the USB that I had warning about its label (made up of some control-character sequence, starting, I think, with ^17). Since installation was complete, and in prior attempts the label was changed, I did not think it was a problem. Now, I'm not so sure! Regards, William.
