1. Keep the kernel image on non-writable media as well.

2. If the kernel is compromised, then kernel-level protection doesn't help
you either (the above was a reference to the claim that user-level daemons
couldn't be trusted). You're screwed unless your defense is implemented
in hardware (which is basically equivalent to putting the kernel and
security daemons on non-writable media).
