This issue will serve as a tracker for individual issues.

To make porting KRF to other kernels easier, we'll need to provide abstractions for (at least) the following operations:

Setting various configuration variables (krf_rng_state, krf_probability, others in config.c). We currently use procfs for these on Linux.
Replacing a syscall at a given slot and reverting that slot back to its original call.
Twiddling cr0 (on systems where necessary).

Some potential challenges:

All targeting is currently done via personality(2), which is Linux-only. Configurable targeting strategies #9 will fix this.

We should also take a peek at https://github.com/roachspray/fkrf and see if we can learn from their experience porting to FreeBSD.
