The previous discussion on that was at:
http://lists.gnu.org/archive/html/bug-coreutils/2009-04/threads.html#00174
and the corresponding diagnostics supression patch at:
http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=941bd48

I'm inclined to agree there should be some diagnostics.
Perhaps we could output diagnostics as normal, but only
try the operation once that gives ENOTSUP?

thanks,
Pádraig.
