Hi,
 
I'm sorry... the problem while trying to mount CD is not an anaconda's failure cause it happens befor running anaconda

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

/Luca
