Thanks for the detailed explanation.
As I mentioned later, the problem seems to be more lated to the NFSv4 server

We switched to NFSv4 in the hopes that it would solve this. And, in fact, it
does if the server is running FreeBSD.
But on Linux, not only does the ACL (which we never set) appear to cp not to be
“trivial”, but it fails to set. I’ve added some details below, if it’s of any
interest.
We were already in the process of switching our NFS servers from Linux to
FreeBSD anyway, so this will just accelerate the process.
Thanks,
