Subject: [PATCH] debug: don't set resource hard limit to zero
Setting the resource hard limit to zero is irreversible, meaning if it
is set to zero then there is no way to set it higher. This means
enabling core dump is not possible, since setting a new resource limit
for RLIMIT_CORE would fail. By only setting the soft limit to zero, we
can disable and enable core dumps without failures.
This fix is present in both main and 3.0.x upstream branches.
