Upgrading Fedora kernel

[Jason Riker]

Hello.  Does anyone have a good link or white paper on upgrading the current Fedora kernel to one of the release candidates?

Thank you.

Step 1: rpm -i <kernelrpmpackage>

Step 2: Reboot.  Select the new kernel from the GRUB menu.

That's the only documentation you need.

Be certain you use "rpm -i" and not "rpm -U", so its a new installation of the
kernel, otherwise he will upgrade your current kernel and you can not go back
to the old situation in case of any problems...

Good luck,

I'm hesitated. Will it retain all the kernel module from previous kernel?

Thanks all for the replies.  However, I'm not sure my first e-mail was
clear.  What I'd like to do is learn how to patch from my current Fedora
kernel up to the latest release-candidate.  I don't have a kernel rpm to
use.  I'll need to do this by hand.

Thanks again.

You don't patch the Fedora RPM installed kernels, you install the next
released version and use it instead.

So, ever so slightly expanding on a prior two-step process:

1. Download the kernel RPM.
2. Install the kernel (as it said before, rpm -i name-of-file.rpm).
3. Reboot and use the new kernel.

Want to add my question to the kernel removal talk.
When i have compiled my own kernel, i want to sweep up the files the
default kernel has on my system, how to do that?

It's a good idea to keep at least one Fedora kernel on the system: it's
there for testing purposes, or if anything goes wrong with your
self-compiled kernels (like over-writing the kernel image without
installing the modules just after there's been an incompatible ABI
change in the IDE code...)

You should also note that (on my system):

$ rpm -q --whatrequires kernel
initscripts-8.11.1-1
lvm2-2.01.08-2.1
hal-0.5.2-2
hal-0.5.2-2
prelink-0.3.4-3
pcmcia-cs-3.2.8-4.12
quota-3.12-6
rp-pppoe-3.5-27
gnome-volume-manager-1.3.1-1
libpcap-0.8.3-13.FC4
nfs-utils-1.0.7-11

(i.e. these packages require at least one kernel RPM installed).

The Fedora kernels you have installed can be identified with
$ rpm -q kernel
kernel-2.6.11-1.1369_FC4
kernel-2.6.12-1.1387_FC4
kernel-2.6.12-1.1390_FC4
kernel-2.6.12-1.1398_FC4
kernel-2.6.12-1.1420_FC4
kernel-2.6.12-1.1447_FC4

and uninstalled with
# rpm -e kernel-2.6.12-1.1387_FC4

If you really want to get rid of all Fedora kernels, then you have these
options:

* making an RPM out of your custom kernel and installing that instead.
   (preferred: investigate make rpm)

* uninstalling the last Fedora kernel with rpm -e --nodeps

* identifying all files in the last RPM with 
   rpm -ql kernel
   and manually deleting them.

Hope this helps,

James.
