Yes. Note that AUFS really has a number of issues besides this and you may
want to look into ways to get rid of this.

Ok, good. The changes between 1.0.18 and 1.1.0 are really minimal though,
it may be a good idea to try merging triblade-2.6.28 into your 2.6.30
tree to see if that still works. I can also provide a triblade-2.6.30 tree
so you can check that against your version and possibly send patches
where it differs from the working version.

If problems were introduced between 2.6.30 and 2.6.32, I should probably
have a look at changes in powerpc interrupt handling in that time frame.
