The kernel sets RLIMIT_CORE to 0 by default. Let's bump this to unlimited by default (for systemd itself and all processes we fork off), so that the coredump hooks have an effect if they honour it. Bumping RLIMIT_CORE of course would have the effect that "core" files will end up on the system at various places, if no coredump hook is used. To avoid this, make sure PID1 sets the core pattern to the empty string by default, so that this logic is disabled. This change in defaults should be useful for all systems where coredump hooks are used, as it allows useful usage of RLIMIT_CORE from these hooks again. OTOH systems that expect that coredumps are placed under the name "core" in the current directory will break with this change. Given how questionnable this behaviour is, and given that no common distro makes use of this by default it shouldn't be too much of a loss. Also, the old behaviour may be restored by explicitly configuring a "core_pattern" of "core", and setting the default system RLIMIT_CORE to 0 again via system.conf.
