OVH: How to upgrade your kernel, if using Grub2

OVH, the hosting company where I have my dedicated serves, does some quality assurance on the Linux kernels, the ones it deploys on newly installed servers.

Now, after more than a year, there has been a new release. This is how upgraded the kernel on my Gentoo servers, which use Grub2:

# cd /boot
# wget ftp://ftp.ovh.net/made-in-ovh/bzImage/latest-production/bzImage-3.8.13-xxxx-grs-ipv6-64
# wget ftp://ftp.ovh.net/made-in-ovh/bzImage/latest-production/System.map-3.8.13-xxxx-grs-ipv6-64

# grub2-mkconfig -o /boot/grub2/grub.cfg
Generating grub.cfg ...
Found linux image: /boot/bzImage-3.8.13-xxxx-grs-ipv6-64
done

Then reboot…

If you use Grub2, regardless of the distribution, it should work the same.
