13:58:20 < BenC> siretart: "crashed" is a loose word in this context, since 
unionfs didn't crash either
13:58:34 < BenC> siretart: what exactly happened when you tried to use unionfs 
(in what way did it fail)
13:58:45 < BenC> aufs I mean
13:59:21 < siretart> I have to admit that I can only tell from memory. I gave 
it a quick shot, and on the first glance, it looked 
                     like aufs wouldn't work with NFS at all
13:59:29 < BenC> If we can give you an updated aufs to resolve this, we can do 
that...but updating unionfs to work with NFS is not 
                 going to happen
13:59:42 < siretart> hm. I see
14:00:18 < BenC> siretart: how hard is it for you to download and build latest 
aufs with our kernel headers and test it for fai?
...
14:03:54 < siretart> ok. will try that. thanks!


** Also affects: fai (Ubuntu)
   Importance: Undecided
       Status: New

** Description changed:

  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/sources.list.
+ 
+ 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.

** Changed in: fai (Ubuntu)
