+In the past, Lix disabled core dumps by setting the soft `RLIMIT_CORE` to 0
+unconditionally. Although this rlimit could be altered from the builder since
+it is just the soft limit, this was kind of annoying to do. By passing
+`--option enable-core-dumps true` to an offending build, one can now cause the
+core dumps to be handled by the system in the normal way (winding up in
+`coredumpctl`, say, on Linux).
