Bug#267553: kernel does not install from nfsrooted environnement

[Fabrice LORRAIN]

Package: kernel-image-2.6.7-1-686
Version: 2.6.7-2
Severity: normal
Hello,
I try to install. a new i686 box under sarge with our custom nfsroot 
environnement. The installation of the kernel failed with the following:

# apt-get install kernel-image-2.6.7-1-686
Reading Package Lists... Done
Building Dependency Tree... Done
kernel-image-2.6.7-1-686 is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
3 not fully installed or removed.
Need to get 0B of archives.
After unpacking 0B of additional disk space will be used.

  Package kernel-image-2.6.7-1-686 is not configured yet.

E: Sub-process /usr/bin/dpkg returned an error code (1)
Same problem with kernel-image-2.4.26-1-686.
The exact booting order was the following :
- Netbooting (PXE) the box,
- partitioning
- tar xzf sarge.tgz /mnt/out (home build sarge-base tarball)
- chroot /mnt/out
- mount /proc
- apt-get {update,upgrade}
- install some packages
- apt-get install kernel-image-2.6.7-1-686
Right know it seems I cannot install sarge from a nfsroot env without 
building my own kernel... I do feel the severity should be higher. 
Leaving it at your appreciation because of the freeze.
