A faculty member here would like to make use of virtual Debian machines
running on an S/390 system in his OS class. He'd like his students to
run through several exercises in which they make changes to the kernel.
I'm not familiar with the process involved, and directed him to
http://kernel-handbook.alioth.debian.org/index.html#contents for
starters. Are there other or better resources?
The faculty member does not have much Debian experience. Neither do I.
Is the process involved in rebuilding the kernel pretty straight
forward, or full of problems and "gotchas"?
