Hi CC,

thanks a lot for you help...

however by now I'm not able to perform the installation 
owing to anaconda failures on mounting or umounting the CD 
:(

Hi Luca

'grubby' is the tool to automate 
modifications to /etc/grub.conf (and the config files of other boot 
loaders).

Amongst other things, in my %post section I 
have

grubby --grub --update-kernel=`grubby 
--default-kernel` --args "${KERNEL_PARAMS} root=LABEL=/" 

Where $KERNEL_PARAMS are programatically 
determined previous in the %post section.

Hope this helps.

CC

Hi CC,

the only reason that let me modify kickstart 
files in order to add kernel parameters is that it was the only way I knew 
to do it 

do you think it should 
be better using grubby? I'll try this way too.

thanks

Hi 
Luca

Is 
there a reason you can't call grubby from the %post section to add the 
parameters you need?

  Hi Tom,

  now it can start but soon anaconda breaks reporting the 
  following Exception: 

  "An error occurrder unmounting the CD. Please make sure 
  you're not accessing /mnt/source from the shell on tty2 and then clik OK to 
  retry"

  Shell on tty2 is on /

  from /tmp/anaconda.log file I see 
  this:
  ...
  ...
  * moving (1) to step readcomps
  * exception in unmountCD: (16,'Device or resouce 
  busy')

  I did the following steps:

  - modified isolinux.cfg file to add the kernel parameter 
  I need
  - modified some .msg files to customize this new CD 

  - modified the kickstart files to add the kernel 
  parameter to boot loader (as I did yesterday)
  - recreate the ISO

  Any ideas? I really don't known how to investigate on 
  it...

  thanks

  You have to modify 
  the syslinux files on the boot CD and rebuild the CD. Change the append= lines 
  and add the option you need.

  Thanks,

Subject: kernel 
  parameters

  Hi all,

  I'm upgrading a bootable CD 
  which uses kickstart to automatically install REHL4 Upgrade3 and a subset 
  of programs.

  The upgrade is needed by 
  a new hardware that requests a special kernel parameter to boot the 
  system (in particular the kernel parameter is 'pci=nommconf' and it should be 
  needed to use the Smart Array Controller)

  I've been able to add this 
  parameter in kickstart config file and now the boot is working fine (I'm using 
  GRUB as bootloader), but I must type the kernel parameter by hand at 
  installation prompt...

  Is there a way to configure 
  kickstart (or something else) in order to autamatically pass this kernel 
  parameter to installation process too?

  Thanks 

  Regards
