I think I'm good either way and asked a bit about this during the last
developers meeting. I just need to know if the preference is to
provide a kernel or build it each time. If we start using more
pre-builts, probably need a way to version control those and
For this test it is quite time consuming already so the kernel build
is in the noise. Plus your point is valid that we don't have a least
two examples where we would have this in common (yet). I'll
consolidate this in with the test in my next version.
Thanks for the review!
