Of course.
The * in the limits.d file is a “domain” value you can adjust to suit:

You’d have to read the systemd docs to figure out the defaults for LimitCore,
but I suspect you don’t get cores until you set this on a per-service basis.
You can also adjust the sysctl pattern path to put cores somewhere secure.
That’s the normal use of absolute paths: put the cores into a dropbox directory
that only root can read but anyone can write to.
Also, I should point out that my first step, removing ABRT, is a heavy-handed
method. Maybe what you *actually* want to do is learn to cooperate with ABRT
rather than rip it out entirely.
