zmg rp ... with autoreboot?

hi,

we install our images with a zenworks-boot-cd (zcm 11.2) in manual mode with:

img rp <serverip> <imagename>

After the Image Engine runs through (blue background with progress bar) we get the linux-promt where we enter reboot.

Is there any way to automatically reboot after the engine is done? Some command line option for img or a shell-trick?

thx,
hugo
