You would use it like this to update only the kernel on the image: $ jam update-image kernel I don't think we can currently only update the system folder and leave everything else untouched. That might be something we want to change in the future, though. As a work-around, you can create a second image, boot from that one, mount the first one, and replace the "beos" folder on the root level of the first image. Bye, Axel.
