What's the best way to go about upgrading the kernel?

uname -r
2.6.18.8-x86_64-linode1

I didn't realize I was behind until I looked at available kernels.

How do I upgrade?

You can select a kernel in the boot settings of your configuration profile. Changing it will require a reboot to take effect. You can either select a specific kernel or one of the "Latest" options to automatically update over time (at least as of your most recent reboot).

Set your linodes profile to use "Latest 3.0" in the linode manager and reboot

What about if you are using a custom or distro kernel? How can you upgrade. I have asked a couple of people before if apt-get update and install does the kernel. They thought it probably did but could not be sure.

As long as /boot/grub/menu.lst is updated accordingly, pv-grub should pick up on your new kernel and boot it. Refer to the library for details.

I think i did that already its just I was wondering about upgrading that kernel , i.e not changing the kernel I used but updating I guess . Sorry If I am using the wrong terminology. I did actually follow the linode guides for using pv grub etc and it seemed to work without any problems.[/list]

If you're using Linode's kernel, a reboot will get you the latest kernel. If you're using a custom kernel, it works just like it would on a real linux server, and pv_grub will pick the default kernel you've selected.

To update the kernel, update it normally with apt-get, yum, or whatever else your distro uses, and make sure your grub menu list has the right kernel as default.

As a warning, though, you shouldn't be using a custom kernel unless you have a specific need to do so.

I had the idea to use selinux, even though I am not really competent but for the time being it is going ok. I'll reboot into the linode kernel if I have issues. I was advised also to use aptkeeper which I intend to do.

Do you know what kind issues I might face if I were to boot with the linux kernel now that I have been using the distro kernel?
