 * Kernel options

If you want to edit kernel options, note that the following are currently broken with Kerrighed:
{{{
    * General setup -> IPC Namespaces
    * Processor type and features -> Preemption Model -> Voluntary Kernel Preemption
    * Processor type and features -> Preemption Model -> Preemptible Kernel
    * Networking -> IrDA (infrared) subsystem support
    * Security options -> Enable access key retention support
    * Networking -> Networking options -> The Ipv6 protocol 
}}}
Note: don't forget to add NIC driver and, if you plan to use NFSROOT, include it in the kernel, not as module.

 * Kernel options
{{{
    * Cluster support -> Active Fork Delay  (Can't compiler, maybe this function doesn't release)
}}}
 
 * Enable SMP (Kerrighed default .config don't enable it, you must choose CONFIG_SMP)
{{{
   * Processor type and features -> Symmetric multi-processing support
   * Processor type and features -> ( ) Maximum number of CPUs (2-255)
}}}

 * If CONFIG_HIGHMEM64G is set
{{{
kererighed: error: unknow symbol __support_pte_mask
}}}

 * ipcs, can't see anything
