These types of system have limited storage space on the root filesystem. Installing an agent on the root filesystem is deemed to put this limited space at risk. The implementation for these systems creates a project on the internal ZFS storage array in the rack and creates a filesystem for each node or VM that has an agent installed.
The installation on the node/VM will then perform the following:
Update the (v)fstab to ensure the filesystem is mounted from the ZFS storage array at boot time.
Mount the filesystem on the required directory.
