While I don't know that you are still trying aufs, I have found one
thing about ubuntu edgy kernel.
The version of this kernel seems to be 2.6.17 basically, but one
interface (at least) is patched by a part of 2.6.18. It is the arguments
of super_block operation umount_begin().
Since aufs supports both of 2.6.17 and 18, it uses,
#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,18)
/* code for linux-2.6.17 and earlier */
#endif
In ubuntu edgy kernel, this condition didn't work.
Since the LINUX_VERSION_CODE in ubuntu edgy is defineed as 2.6.17, but a
part of code/interface is 2.6.18 actually.
I guess you were warned by your compiler at compiling aufs/super.c,
since the arguments of umount_begin() mismatches.
So you need to fake aufs, at least the arguments of umount_begin() to be
matched.
Here is a patch for it.
But I am afraid you may meet another problem which is related to the
kernel interface which is mixed with 2.6.17 and 2.6.18 in ubuntu edgy.
