Martin,

You can use the attached eas_acls.py to work around this issue (patch  
is in CVS as well). Simply replace the one in your Python installation  
with this file (on client and server) and you'll be good to go.

The failure is happening on the destination filesystem. What does  
mount report there?

Also, what is the rdiff-backup command you are using? It must be  
detecting extended attributes support -- trust me, it has no ability  
to pretend. ;-)

Besides, since the OS reported a 'Operation not permitted' error and  
NOT 'Operation not supported', it further confirms that extended  
attributes are supported at the destination. Besites, getfattr command  
can lie to you -- it does not need to return extended attributes which  
you do not have permission to read (eg, system.*, security.*)
