Well, I thought that it was pretty much crystal clear for anyone familiar with how SSH works from post #51 already that /tmp/root was root's home directory.
I also misunderstood your "Yes, I see that from your post." in post #55 as referring to post #51 (instead of #54, which you obviously meant), which is why I posted reply #56. Maybe "Yes, I now see that from your new post" would have been clearer.
Anyway, let's both stop the nitpicking and post-counting and return to actual problems
