cp -p fails from zfs file system to other file system

[Fabrizio Gabbiani]

To whom it may concern:

If I do a

cp -p /zfs_nfs_mountpoint/sourcefile  /localdirectory/targetfile

the command returns an error in spite of successfully copying the file. 
The zfs_nfs_mountpoint is a ZFS file system that is NFS mounted. The 
localdirectory is not ZFS.

The error message is:

cp: preserving permissions for `/localdirectory/targetfile': Operation 
not supported

It seems that cp should not return an error, since the permissions are 
defined differently in ZFS and non-ZFS file systems.
