It's very convenient to have fatal signals enabled on developemnt platform as this allows to catch problems that happen early in user-space (like crashing init or dynamic loader). Otherwise we may either enable it later from alive taregt console by "echo 1 > /proc/sys/kernel/print-fatal-signals" but: 1. We might be unfortunate enough to not reach working console 2. Forget to enable fatal signals and miss something interesting Given we're talking about development platforms here it shouldn't be a problem if a bit more data gets printed to debug console. Moreover this makes behavior of all our dev platforms predictable as today some platforms already have it enabled and some don't - which is way too inconvenient.
