Where to modify grub timeout?

Archive SUSE Studio / Studio Express
1

Hi,
I would like to modify the default grub timeout (10 seconds) using Custom scripts or Overlay files in the SUSE Studio. It seems that /etc/sysconfig/boot (CONFIRM_PROMPT_TIMEOUT) is not the right place. File /boot/grub/menu.lst is not present in the image. How is the menu.lst created/where to set the timeout?
Thanks in advance.

SUSE Studio, Based on: openSUSE 12.1

Hi
If you start the appliance in Test Drive, you can then modify the
menu.lst file and save the modified configuration menu.lst file.

I tried that but it seems that the menu.lst is overwritten after the file overlay. My menu.lst started with:

[QUOTE]timeout 1
gfxmenu (hd0,0)/boot/message
…[/QUOTE]
But the image (Build->View files) contains:

[QUOTE]color cyan/blue white/blue
default 0
timeout 10
…[/QUOTE]

There must be some script that modifies that. I would like to know its location.

Yast → bootloader which should rebuild (mkinitrd) it. So changing it
manually and running mkinitrd should work as well.

I cannot put “mkinitrd” into the “end of build” script. It ends with the following:

[QUOTE]Kernel image: /boot/vmlinuz-3.1.9-1.4-default
Initrd image: /boot/initrd-3.1.9-1.4-default
device node not found
root device (/dev/vda) not found
There was an error generating the initrd (1)[/QUOTE]

I solved my problem by putting this into the “boot time” script:

[QUOTE]if [ -f /etc/init.d/suse_studio_firstboot ]
then

Put commands to be run on the first boot of your appliance here

echo “Running SUSE Studio first boot script…”
sed -i ‘s/timeout 10/timeout 1/’ /boot/grub/menu.lst
fi[/QUOTE]

It is not optimal, but better than nothing. Thank you anyway, I forgot the possibility to watch modifications in the Test Drive.
Btw. I discovered that the boot timeout is mentioned here. Author of the article left that as an exercise for the reader [wonderful :-\].
