Package: systemd-coredump
Version: 245.4-3
Severity: normal
Tags: upstream

According to the man page of coredumpctl there is no way to delete a core dump
that it manages.  If you find the file name and rm it then it stays in the
output of "coredumpctl list" with status "missing".

It's a reasonable expectation that everything which can be created can be
deleted.  This is especially true of core dumps which can take more space than
desired and which can potentially have confidential data which needs to be
deleted.

It does btw, man sytemd-coredump
"
In addition the storage time of core dump files is restricted
       by systemd-tmpfiles, corresponding settings are by default in
/usr/lib/tmpfiles.d/systemd.conf.
