Hello.
I wanted to share my experience with some of you new to linux ...or so.

I've upgraded the kernel on my redhat 7.3 cpanel box, without a single problem.
Personally, I use apt-get (http://apt-rpm.tuxfamily.org) I recomend it for anyone over normal rpm installs.

so, I just downloaded the 2.4.18-10 RPM, installed it.
then... check what boot loader you have :
# cat /root/anaconda-ks.cfg | grep bootloader
if you see & --useLilo& you're using Lilo ... so you need to update /etc/lilo.conf (remember to put your new kernel as default) and then do
# lilo -v -v

if you have grub, the same, update your files. and restart.

and all okey!

and if someone with better know as me is reading...
is there any place to get a 2.4.19 kernel RPM ?
I wanted to install it .... but.... I really dont want to make so critical changes ... I cant have downtime ... you know. :) so the rpm is the easyest way.

Regards.

oh well... then you dont have anaconda installed ...
you dont have a redhat ... dont you?

You can always ask to you NOC which one you have...

or maybe any linux guru can tell you another way of know this :)
maybe you can just modify for example ... the lilo.conf to replect the changes .... and if you boot again in the same kernel ... then, you use grub.

just ... dont delete your old kernel until you can boot on it. ;)

Regards.

I wrote step by step instructions about Kernel upgrade before, in these two threads

But about Kernel 2.4.19, (at the date of this post) Red Hat hasn't offered Kernel 2.4.19 RPM, they follow this policy &New is not the best always& Stability is their goal, they usually examine the codes, and modify it however you should not to worry about security issues in Kernel, because Red Hat has patched 2.4.18 Kernel and is offering its own builds like Kernel 2.4.18-10

OpenSource does not mean safety always; this is why someone should examine and reduce the risks like Red Hat.

However you can install Kernel 2.4.19 from http://Kernel.org and it is not necessary to have an RPM release
(Useful in case of GRSecurity)
