systemd-coredump+coredumpctl give you pretty easy access to core files, they are just dumped into /var/lib/systemd/coredump/. The advantage is that a) things are logged and can be easily looked up and queried, b) you get a lot of metadata like open files, cgroups, /proc/mountinfo, umask, capability masks, etc., c) a stacktrace is automatically generated and logged locally, d) old coredumps are automatically removed, e) you cannot fill your disk with coredumps. The last two points are crucial for "casual" users, who might want to have easy access to the occasional crash without expending too much attention. Zbyszek
The last two points are solved by setting the soft ulimit to 0, meanwhile systemd-coredump steals away my core dumps and requires privileged operations to retrieve them.
