Neil Horman posted an enhancement to a /proc/sys/kernel interface for redirecting core dumps, "allowing the core_pattern to contain arguments to be passed as an argv array to the userspace helper application. It also adds a format specifier, %c, which allows the RLIM_CORE value of the crashing application to be passed on the command line, since RLIMIT_CORE is reduced to zero when execing the userspace helper". Andrew Morton was skeptical at first, "this all seems to be getting a bit nutty. Who needs this feature and what will they do with it, etc?"
