As of systemd v243 the kernel.core_pattern for systemd-coredump (once
again[1]) no longer includes the hostname, see systemd.git commit:
| commit 47cf786c0a13fccd777c334bed4b1e7b02f18d42
| Author: Franck Bui <fbui@suse.com>

|
| coredump: rely on /proc exclusively to get the name of the crashing process
[1] This is similar to a revert of our commit a78509496d,
which mentioned:
| commit f45b8015513d38ee5f7cc361db9c5b88c9aae704
| Author: Jakub Filak <jakub@thefilaks.net>
| Date: Thu Feb 15 12:12:46 2018 +0100
|
| coredump: accept hostname on command line (#8033)
We can't just revert the change though, as we need to distinguish between
Debian 11/bullseye and older releases, while commit a78509496d was
for Debian 10/buster and older releases.
