Then I suggest that you test the setcap patch that I pointed to earlier,
you'll likely need the pseudo 1.8 upgrade that Joshua sent last night.
This should ensure that setcap works in the pseudo environment.   Then
follow the instructions in image_types.bbclass to ensure that xattrs are
preserved when the image is created, and check your kernel configuration to
confirm that xattrs are supported.  I recommend attempting to use fsetattr
on the target directly to verify this. If all the pieces are in place then
they should work.

There's a number of bugs in bugzilla for tracking these issues (#9859 is
the metabug tracking them).  Your help in solving this would be much
appreciated!
