Well... that was it. What had happened was that I had started the libau testing with the previous kernel version aufs driver build, and technically as libau was still being 'tested', I hadn't written up the changes. So inbetween there is a kernel upgrade, and naturally I follow the normal notes to build the aufs driver... which have the standard Debian state of commented out CONFIG_AUFS_RDU... Its been a month or so so there was no way that'd come to mind as I build aufs (as far as my brain is concerned, libau is just aufs-util stuff), thus this screwup. I've just donated, sorry for wasting your time. Currently testing a single normal rsync daemon call atm, bound to succeed. Thanks
