Well, if the kernel doesn't provide the feature, then we can be sure it
will never be implemented :-)
I thought this was a good place to start asking,, and even if GNU
coreutils opt to not implement this for whatever reasons, other
applications still can (mine will!)
Besides, there are already many tools which use this feature when
available, these would for with no or minimal adjustments.

Thanks, this is what I needed :-) I wondered if there is a specific reason
it's not implemented, or if it was just something no one ever did.

I can start my investigation in the kernel sources ;)

Thanks,
