You really should not do this. The RAMDISK kernel uses the SMALL_KERNEL option, and this can have all sorts of unknown effects. It is castrated Unix, for the purpose of installation. For now, what that option changes in the kernel is fairly limited. But if we start hitting more size constraints regarding the install media space, we the RAMDISK kernel will start violating Unix rules more.
