Hi again, Sorry for the bad formatting in the last msg. I just switched to "plain text", maybe it will be a bit better.
Basically the two only things where I did not follow the README are: - Applying the aufs3-loopback.patch, not mentioned in README - Not doing the "fs-aufs" module renaming mentioned in README A third thing I forgot to mention is that I am using userspace tools from the debian squeeze (old-stable) package "aufs-tools". It used to work perfectly with my old kernel (linux 3.0.50 with aufs patch), and I'm unable to compile the newest aufs-utils for some header issue in /usr/include. Still, I probably shouldn't be able to generate a BUG from a userspace tool. Could any of those 3 things be the cause of the BUG? Thanks, -- François <fdelawa...@wirelessmundi.com> Wireless Mundi S.L.
