Hostname resets on OVH server

Symptoms

The hostname on an OVH server resets at reboot.

Description

The hostname reset is likely due to the cloud-init module being enabled.

Workaround

1. Access the server's command line as the 'root' user via SSH or "Terminal" in WHM.
2. Open the /etc/cloud/cloud.cfg file in your preferred text editor.
3. Change the preserve_hostname value to true.

   preserve_hostname: true

4. Change the manage_etc_hosts value to false.

   manage_etc_hosts: false

5. Save the changes and exit the text editor.
