Currently the TAR installation instructions for the Automation Agents specify to create the directory /var/lib/mongodb-mms-automation.

Some organizations may prefer to avoid using /var/lib.

This can be achieved by applying these steps before starting an Automation Agent:
1. Modifying the "Binary Download Directory" in Settings > Agents
2. Creating that directory instead (and ensure ownership/permissions)
3. Modifying the Automation Agent configuration file to change the default directory path for mmsConfigBackup.

These steps might be located in an "Advanced Configuration" Section in the Reference pages:

• https://docs.opsmanager.mongodb.com/current/reference/automation-agent/
• https://docs.cloudmanager.mongodb.com/tutorial/install-automation-agent-from-archive/

The Download Directory should be consistent across all hosts in the Group.
