So you tested with a script on a local disk and it worked?

That would be definitive.

Also, check whether the NAS mount is *actually* flagged noexec,
regardless of what you think it is or what flags are used to mount it.
Put a harmless executable on the NAS (like cat or echo) and try to
execute it off the NAS...

Also interested in how you are mounting the NAS - is it NFS, CIFS,
something else? Sorry if I messed that in earlier messages.

Also also - is there any chance that another mount is somehow shadowing
your expected mount?

That is certainly weird.

As is is the fact that ALL shebangs are failing.
