but what is the point to break your system to not
automatically maintain grub.conf in this context? what is
the advantage have to add the new kernel manually to the
config?
Good point again Reindl.
I've not broken the system, it's just I want to decide when
the new kernel should be booted.
why in the world do you install it if you do not want it to get booted?
if you do not update the kernel simaply "yum --exclude=kernel* upgrade"
Hi Reindl.
I install it but delay using it untill I decide to activate 
it myself.

My reason is I've had the kernel version change and that has
been buggy and broke my system. So I'd rather take control
myself over when my box moves to a newer kernel version
and what do you think what is "default=0" in "grub.conf"
is for? exactly to specfiy WHAT installed kernel should
be booted
This is part of my grub.conf file Reindl:
default=1
# comment this out to skip the countdown screen
# and go straight to the GRUB boot menu and stop there.
# timeout=300
splashimage=(hd0,13)/boot/grub/splash.xpm.gz
#hiddenmenu
title Initial CentOS 5.5 DVD kernel (vmlinuz-2.6.18-194.el5)
     root (hd0,1)
     kernel /boot/vmlinuz-2.6.18-194.el5 ro root=LABEL=Centos-5-root
     initrd /boot/initrd-2.6.18-194.el5.img
title CentOS 5.8 system (vmlinuz-2.6.18-308.11.1.el5)
     root (hd0,1)
     kernel /boot/vmlinuz-2.6.18-308.11.1.el5 ro root=LABEL=Centos-5-root
     initrd /boot/initrd-2.6.18-308.11.1.el5.img
The timeout is disabled so I can select which kernel to 
boot myself, after updating grub.conf.
I kept the details for the Centos DVD kernel so I can use my 
own grub.conf file if I needed to do a fresh installation of 
Centos.
Kind Regards,
Keith
