You are welcome. The key here was that I could
simply omit the complicated part.
Is there a regression test which compares the result of this function

Not for FSX - which makes sense because there
will be changes to noderev and changed path list
representation at some point this year.
For FSFS, there are a two tests that will fail due
to hard-coded expectations once you omit the
directory representation. If I succeed writing a
"complete" constructor for FSFS r0, I'll add a
regression test to make sure that old servers
will be presented with the same r0 contents as
