Change mount point for /mnt folder in Ubuntu Linux on Azure

Problem

When provisioning Linux VMs on Azure, /mnt folder is automatically created and pointed to Resource Disk. In some case, we need to have more fine-grained control over /mnt folder (for instance for backward compatibility) and map Resource Disk to its sub-folder, e.g. /mnt/tmp

Solution

Azure provides fantastic support for Linux VMs called Microsoft Azure Linux Agent.

sudo service waagent restart

vi /etc/waagent.conf 
# Mount point for the resource disk
ResourceDisk.MountPoint=/mnt/resources 

 Restart waagent service

 sudo service waagent restart
