      .The kdump service fails during boot

      After the installation of `registry.redhat.io/rhel9/rhel-bootc` container image to a physical system, the `kdump.service` fails.

      To work around this problem, ensure the `PrivateTmp` service is disabled:
      [subs="quotes"]
      ----
      # cat /etc/systemd/system/kdump.service.d/override.conf
      [Service]
      PrivateTmp=no
      ----

      Then rebuild and restart the kdump service:
      [subs="quotes"]
      ----
      # touch /etc/kdump.conf
      # systemctl restart kdump
      ----
      Show
