26 includes various WITNESS- related kernel options, INVARIANTS, malloc
27 debugging flags in userland, and various verbose features in the
28 kernel. Many developers choose to disable these features on build
29 machines to maximize performance. (To completely disable malloc
30 debugging, define MALLOC_PRODUCTION in /etc/make.conf, or to merely
31 disable the most expensive debugging functionality run
32 "ln -s 'abort:false,junk:false' /etc/malloc.conf".)

35 If you are running a -CURRENT kernel since r273872 (Oct 30th, 2014),
36 but before r278950, the RNG was not seeded properly. Immediately
37 upgrade the kernel to r278950 or later and regenerate any keys (e.g.
38 ssh keys or openssl keys) that were generated w/ a kernel from that
39 range. This does not affect programs that directly used /dev/random
40 or /dev/urandom. All userland uses of arc4random(3) are affected.
