I agree, I also think that there was a pre-existing inconsistency
there, but `rename-file` would cover it up later on. But trying to do
it manually, complicates things in this regard as well.

I understand that concern too. But we don't even understand well (as
far as I can see) why it fails when crossing filesystems, and are
already rushing to a workaround. I just offered some respectful
resistance. And if, after all, the decision is not to touch
`rename-file' because it's risky, so that a workaround is really what
is intended, I'll get that.

Get well soon! :-)
