Hi Martin - Linux NFSD does not support alternate data streams because none of the underlying file systems on Linux implement them. Very much like the HIDDEN and ARCHIVE attributes. I believe Solaris and their storage appliance are the only implementations of NFS that do support them, since they have implemented streams in ZFS. Instead, Linux NFSD implements extended attributes (that's what our native file systems and user space support). I realize that the semantics of those are not the same as stream support. -- Chuck Lever
