update-ovh-kernel

Kernel updater script for OVH dedicated servers.

This checks the OVH FTP (ftp://ftp.ovh.net/made-in-ovh/bzImage/) for new kernel versions, downloads and installs them.

Installation

Clone the repository, and add a root-owned copy of update-ovh-kernel.sh to your crontab. I suggest a daily execution.

The script has a few configurable options, at the start of the file.

INSTALLED_KERNEL_FILE is a file where the currently installed kernel version is written. It is updated when a new kernel is found and downloaded.
KERNEL_DIR is the folder where the kernel images are downloaded.
KERNEL_VARIANT is the kernel suffix. See ftp://ftp.ovh.net/made-in-ovh/bzImage/latest-production/ to find what variants are available.
KERNEL_CHANNEL is the kernel channel. At the time of writing, the available options are experimental, production and test See the symlinks in ftp://ftp.ovh.net/made-in-ovh/bzImage/ for the full up-to-date list.
NOTIFY_REBOOT_REQUIRED_COMMAND is the command run to notify the system of a required reboot. Unset it if you do not want this.
UPDATE_GRUB_COMMAND is the command run to reload the boot manager configuration, after the new kernel image has been downloaded. Unset this if want to do a manual install.
