(9load now is able to pxe load the plan9.ini file.) i'm not most people, but i like having plan9.ini. it elimates guesswork about which kernel was started. i wouldn't like a 9load that made plan9.ini optional and guessed which kernel to run and which fs to use. also, there's a very good reason for having a seperate kernel and drivers for 9load. pxe booting all but one's core machines is definately the way to fly, but pxe images are limited in size. i'm not sure what the maximum size is (the minimum guarenteed size is 64k), but i have not been able to directly load modern plan 9 kernels on our hardware. instead of making 9load as close to the plan 9 cpu kernel as possible, i would use bios instead of drivers. the bios already knows how to talk to pxe-capable nics, and storage with boot rom. this would require writing a real mode assembler.
