10.8.2 - Can't turn off hibernation any longer...

Before 10.8.2, I could run the terminal command below, and turn off hibernation. This would save 8GB of hard drive space for the sleep image.

sudo pmset -a hibernatemode 0

However, after each restart, the sleep image is created again, even with the 0 setting as above. I have to rund the command below to remove it, but it's useless now as it's created each restart.

sudo rm /var/vm/sleepimage

Is there any way with 10.8.2 to turn off hibernation for good?

Thanks,

Bryan
