[rdiff-backup-users] Errors between rdiff-backup and NTFS-3G 2009.2.1?

[Matthew A. Thompson, Contractor, Code 6189]

Previously, I had asked this list about this error which occurs when 
trying to backup to an external NTFS drive:

http://pastebin.ca/1342055

Blame seemed to be placed on attr and libattr which had just been 
updated that day.  However, regressing libattr had no difference.

I then looked back at my yum log and saw that NTFS-3G was updated a few 
days earlier. Since I rebooted right before this error occurred, perhaps 
mounting my external drive NTFS-3G upon reboot had caused it.  Checking 
NTFS-3G's site we see:

http://www.ntfs-3g.org/releases.html

STABLE Version 2009.2.1 (February 12, 2009)
<snip>
# Change: The user extended attribute namespace is supported by default 
on Linux.

The release notes on this point states:

The user namespace extended attributes are supported from now by default
on Linux. The other namespaces like system, security, and trusted, are
supported by the Advanced NTFS-3G driver. Please see more at

    http://pagesperso-orange.fr/b.andre/advanced-ntfs-3g.html
and
    http://pagesperso-orange.fr/b.andre/extend-attr.html

I read this to mean that "streams_interface=xattr" (or something) is 
default and NOT "streams_interface=none" as was true before.  So I try:

# mount -t ntfs-3g /dev/sdd1 /media/LaCie -o streams_interface=none

and, voila, I can backup!

My question now is, should I just always mount as 
"streams_interface=none" or is there something I can change with 
rdiff-backup to allow me to now use the new default mounting option of 
"streams_interface=xattr".

Thanks,
Matt
