In that case, I'd suggest using devroot since it's useful
to know how things get bootstrapped and having a
small set of files in the kernel image is a handy technique
for embedded applications.  Although it doesn't talk to
any disk devices, you can point to the next tutorial and
explain that most file systems run as user applications
and communicate with the disks by way of 9p.
