[Unionfs] kernel oops when defining more then one unionfs over tmpfs

[David Peer]

Hi Erez and Rene,


Thanks for your reply.

My problem is same as Rene's except that my root fs is over nfs 
repository that many machines

use it as their root directory.

This is why I use unionfs over /etc and /var for each machine.

I define tmpfs for the RW portion for /etc /etc_rw, and for /var  /var_rw.

I hope the kernel trace will help.
