I use yum on my Centos boxes to do kernel updates. You need to edit your configuration file to allow kernel updates.

Here's where I found out how to upgrade from 3.3 to 3.4

Using your favorite *nix text editor, such as vi.

If the file already exists it's probably yum.conf or thereabouts. Try searching for it.

is it safe to do kernel upgrades?

It is relatively safe when doing upgrades within the same code base (e.g. 2.4.29 -> 2.4.30), however upgrades from say 2.4.30 -> 2.6.11.8 might require more careful scrutiny making sure all packages on your system are compatible etc.

This is where FreeBSD made it a sinche(sp), since both kernel and OS itself is developed and released together, there is no seperationg between development (in most senses).

It's probably safe to do kernel upgrades with YUM, as YUM shouldn't let you do an upgrade that will break your system.

Of course that limits you to kernels and modules compiled for your OS and version.

Exception:
It's NOT okay to upgrade kernels if your system uses any hardware not supported in your distribution's linux kernel tree. For example, if you've got a special kernel mod for an ethernet port, or perhaps for a SATA drive or RAID configuration, then updating the kernel gives you a good chance of breaking the support for that particular hardware.

Hardware RAID is especially problematic with kernel upgrades.

If you had to make special modifications to your kernel to get the stuff work, then it could/will be a problem. If it worked from the start it will probably work after upgrading assuming you also follow any upgrade instructions/warnings from the provider of the software/hardware
