I'm using lilo to boot my server.
is it possible to give a command to boot the next time to linux.bak, instead of the normal linux.
I want to test a kernel, and if it goes to kernel panic i just give a reboot and then it has to boot to the normal linux again. Is this possible???
Thanks
I understand there is a man for it. What i want is a 1 time boot with the new kernel. If it doesn't come online again i reboot it with my reboot switch and it has to use the old profile again. As far as i can see this isn't specified in the lilo man.

Command is as follows.
Call data center, and get someone to hold down CTRL key to get LILO prompt, and then ask them to switch to good kernel.

lilo -R details
Will reboot to new kernel. If it doesn't come up correctly reboot the machine and it will come back up on the old kernel.

Thanks, that's what i was looking for :)
Is this option also available with grub
For example, i installed a new kernel, but it goes into kernel panic, how do i boot again in the old kernel after a power reset.
I couldn't find the -R option for grub.

Anyway, what is the exact command if I am going to boot the second one which label 2.4.21?
cat /etc/lilo.conf
prompt
timeout=50
default=linux
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
message=/boot/message
lba32
image=/boot/vmlinuz-2.4.20-18.9
label=2.4.20-18.9
read-only
initrd=/boot/initrd-2.4.20-18.9.img
append="root=LABEL=/"
image=/boot/vmlinuz-2.4.21
label=2.4.21
read-only
initrd=/boot/initrd-2.4.21.img
append="root=LABEL=/"
image=/boot/vmlinuz
label=linux
read-only
root=/dev/hda5
image=/boot/vmlinuz-2.4.20-8
label=linux.old
read-only
root=/dev/hda5
image=/boot/vmlinuz-2.4.20-18.9
label=linux-up
root=/dev/hda5
read-only
initrd=/boot/initrd-2.4.20-18.9.img
Is it the following?
lilo -R -D 2.4.21
I am also interested to know the grub option similiar to -R in lilo... anyone know?
Thanks.
Kindest regards,
Choon
