Did NetApp tell you that they'll add support for using the NFSv4 LINK
operation on source objects that are directories?! I'd be extremely
surprised! Or did they only tell you that they'll add support for
using the NFSv4 REMOVE operation on non-empty directories? The latter
is definitely feasible (although it could fail due to share deny OPENs
of files below, say, but hey). The former is... not sane.

Oh, I see. But you still don't want hardlinks to directories!
Instead you might be able to use LD_PRELOAD to emulate the behavior
that the application wants. The app is probably implementing
rename(), so just detect the sequence and map it to an actual

So Solaris is just a fileserver here?
