upgrade kernel OpenSuse 10.3

i'm newbie in lamp, i using OpenSuse 10.3 in my linode 360,

i read the documentation about "Zypper", when i run "zypper up", it's recomended to upgrade my kernel. see message below :

> kernel patch license:

This update can be used to install a new kernel.

If you decide to use the kernel update, we recommend that you reboot

your system upon completion of the YaST Online Update, as additional

kernel modules may be needed which can only be loaded after the system

is rebooted.

i tried to googling, upgrade kernel in VPS is a bad idea.

it's safe to patch the kernel in linode?

thanks.
