Hello,

I don't have the latest (I have a 2.6.32 kernel with the AUFS patch) but
I'm experiencing problem which is generic enough not to be dependent of
the latest release.

My root folder, which is prepared in an initramfs, is an AUFS merging a
read-only squashfs and an overlay write folder:

mount -t squashfs -o loop /disk/a.squashfs /root-ro
mkdir /disk/overlay
noatime,br:/disk/overlay:/root-ro=ro none /root

Once the system has booted (/root of the initramfs becomes the /), I
need to insert a module into the kernel a module:
insmod module.ko base_img=/image.dof
This modules requires and loads/uses many files (image.dof but also some
others) which are "physically" on the squashfs and "served" through the
AUFS.

If I do this, the kernel crashes. It makes sense to me as the module is
as "low" as AUFS. Temporarily, my hack is to copy the files into a tmpfs
and use those versions.

Is there another way to solve my problem without using a tmpfs? Can I
make a hole in AUFS?

Grégoire
