kernel parameters

[Mariani, Luca]

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
	 
	/Luca

	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
