Yes. I've renamed it into --from, and extended the manpage documentation
on it.

Possible inputs are all kinds of hwloc objects which have a unique
occurence in the tree. It's thus the correct current list (more may come
in the future).

Mmm, I think the problem is because --ignore is passed as such to the
hwloc detection code, which then misses the second NUMA node:
$ lstopo --input ../hp-dl980g7-01 --ignore machine
will indeed not show the second NUMA node.

They surely are not dummy questions, as they actually even raise issues :)
