Understood, so this is probably not a bug and just a feature, but why
does a Linux client try and then generate application level errors?
A Solaris client is willing to NFS mount vers=3 a ZFS filesystem and then
run GNU cp -rp, for example, without complaint. Perhaps there is a simple
method determine if ACL's are available/supported on a particular NFS
mount?
