Ah... Bloody hell. I double confused myself. RSX do show nodes without a
name, and which are known to be unreachable, when you request known nodes.
My confused postings happened because when you do a output to a file
from NCP in RSX, the output actually gets appended to a file, and does
not create a new file, and I accidentally directed output to already
existing files that had been done earlier with similar commands, so I
was actually looking at old outputs... :-/
