Currently Lix doesn't let you enable core dumps from builds to land in systemd-coredump. They are disabled "by default" (except nobody thought to actually put in a setting to retain them):

	`/* Disable core dumps by default. */`
	`struct rlimit limit = { 0, RLIM_INFINITY };`
	`setrlimit(RLIMIT_CORE, &limit);`

It's true that one can change the rlimit from inside the derivation since it is setting the soft limit, but this is inconvenient and sometimes impossible.

The action item on this would be to add a setting that enables core dumps and sets the soft limit to unlimited as well.
