RHEV - node in maintenance mode automatically joins RHEV after reboot

I believe this behavior started with 3.1, and I may be experiencing an irregularity.

When I am planning to reboot my RHEL Hypervisor, I will put it in Maintenance mode (and wait for RHEV to evacuate the VMs).  To my surprise, when the node comes back up - it has automatically rejoined the cluster and will be online.

I would prefer that I have to take it back out of maintenance mode.

Has anyone else noticed this?  Do others share my preference (having persistent maintenance mode through reboots)?

Thanks!
