Err, normally guests read things out of the a guest disk image (think most VMs like VirtualBox, etc.). userboot.so is looking in the guest's disk image. Now, userboot isn't memory limited like the BIOS boot, so if it's possible to have userboot just include both lua and forth perhaps with some auto-detection based on what is in /boot/loader.rc to determine which interpreter to use, that is really the best path forward. -- John Baldwin
