Jun 17 at 17:38 comment added rsaxvc Sounds like TSG is running RHEL9/AlmaLinux9 rather than RH9.

Oct 26, 2024 at 20:10 comment added TSG Wow this is more complicated than I expected (general feeling about systemd). I think I'll close this as solved, and investigate the tmpfiles.d seperately
Oct 26, 2024 at 18:59 comment added telcoM /usr/lib/tmpfiles.d/systemd.conf tells systemd-tmpfiles to delete any core dump files in /var/lib/systemd/coredump/ older than 3 days, and systemd-tmp.conf will tell it to further remove some files from that directory on every boot. To override, copy the systemd.conf and systemd-tmp.conf from /usr/lib/tmpfiles.d/ to /etc/tmpfiles.d/, then remove or comment out the lines referring to /var/lib/systemd/coredump in the copies. The originals will be replaced each time the systemd RPM is updated, so only overriding the config files via /etc/tmpfiles.d makes the change persist.
Oct 26, 2024 at 17:19 comment added TSG Getting very close based on your post - I updated my original question with more information. Only problem left is the core file disappears on reboot.
Oct 26, 2024 at 9:41 comment added meuh The /etc/systemctl.d/ directory does not have to exist if no one wants to override the corresponding files in /usr/lib/sysctl.d/. Is RH9 the same as RHEL9? doc

Oct 25, 2024 at 23:53 comment added TSG The /var/lib/systemd/coredump/ has no files, my OS does not have a /etc/systemctl.d/ directory. I don't think this works for RH9 family
