node powered off after reboot from rescue mode

I acquired a node, and put it into rescue mode.
I used the system a bit, and then it hit a kernel crash.
I did a hard reset via ipmi, and expected the system to come back up into rescue mode.
Instead, the system booted and powered off.

On the console I saw:
[ 55.390845] cloud-init[2851]: Powering node off.

Ie, cloud-init was probably told to power off via power_state.
