The Kernel Is a Pretty Good Development Environment, Isn't It?

At the moment, it is all of the modules you would normally expect like drivers and things. And then I wrote a small module to because by the time we actually need to mount the root file system, it's extremely late in boot. Modules can attach as long as they're available in the ROM. So we pretty much just like attach everything that we can and go and look for the disk device or Ethernet NIC. Almost all of the code is just existing subsystem code that we're just calling into.
