First, an observation: illumos has a modular kernel. Therefore, in order for it to access a file system (the rootfs image in this case) it needs to load the file system driver modules. which it does by reading the filesystem... Normally, it has external help, specifically from the bootloader. Which leads to the second thing, which is a question: what are you trying to do here? It sounds like an interesting experiment, but I'm not sure what the objective is. > I was thinking the second option would be better. > > Is this possible?
