Bug Description
Binary package hint: linux-image-generic
System: ubuntu hardy kernel version 2.6.24.10.8
Steps to reproduce:
mount an NFS share, and use Unionfs to mount an tmpfs over it.
Symptoms: New files can be created as expected, however editing existing files fails with "No permission to write to $file".
This avoids using installation methods like fai, that use this technique during install time. E.g. it fails to setup /etc/resolv.conf or /etc/apt/
UPDATE: we need to switch to AUFS. live-initramfs does already have support aufs support, so it is just a matter to switch it on.

The unionfs in hardy is an older 1.4 version, just used for basic unionfs and live-cd. If you want better unionfs, use aufs instead, which has support for NFS overlays.
