Re: [SOLVED] Re: custom kernel from kernel.org

[mettler]

hi,

I'am trying to setup XEN-Domains via FAI.
So i installed the xen-sources and added aufs-modules to initramfs.conf

But initramfs does not add the module to a *-xen kernel. ?!

I can boot the Domain, everything works fine, except the aufs-read-only
mounts.
So i patched aufs support into my running Xen Kernel. (as module and into
the kernel), but FAI does not mount it correctly.

When FAI is done and gives me a console, i can mount aufs volumes (without
any modprobing).

I probably have to change something in my nfsroot?!

Any hints appreciated ;)

 Just use a plain 2.6.27 kernel from lenny inside the etch
 nfsroot. Therefore create a local repository, that inluced then needed
 deb files. That should work. Also make sure you have a new
 live-initramfs
 package inside the nfsroot. You do not need to comile a kernel on your
 own.

 Hi,

 thanks a lot, after adding some more lenny packages:
  aufs-modules,
  aufs-tools (libc6, tzdata)

 and adding module aufs to be included in the initramfs everything works
 fine.

custom kernel from kernel.org

[Christian Quast]

Hi,

I have a debian etch server used as debian mirror and fai 'master'. The
fai-nfsroot is also debian etch. The installation 'targets' are debian etch
as well as ubuntu hardy.

The problem I am having is that some of the computers I need to install 
use a

PCIe Sata-RAID controller which is not supported by the stock etch kernel
(2.6.18). Hence, during the installation the harddisks connected to the
controller are not recognised by the OS. However, the controller is 
supported

by the newer kernels (= 2.6.20).

So I tried to follow the instructions at [1] to build a custom kernel.
However, I am not really sure if these instructions apply to current fai
versions, missing directories and config file entries. I managed to get the
kernel into the nfsroot and added it to tftp as well. It started booting 
but
the installation process failed shortly after reaching the fai 'screen'. 
If I
remember correctly fai(?) complains about missing write permission on 
lots of

files / directories.

Reading the thread 'regular kernel' posted a few days ago I figured this 
might
be due to the incompatibility mentioned by Michael Tautschnig. So I 
tried to
build my own kernel. I have tried building unionfs 2.x [2] as well aufs 
[3].
When I apply either of these 'patches' to the stock kernel from 
kernel.org (I

tried 2.6.26/27) I get an error during compilation.
   ERROR: security_inode_permission [fs/aufs/{aufs,unionfs}.ko] 
undefined!


I couldn't find any helpful links searching the internet.


So my questions are:
What are the required steps to create a custom kernel  2.6.20 used 
during the

installation?

Should I build a new nfs root wich is based on something other than debian
etch?

Is there a way to use fai without the need to use unionfs (etc...)?
