    Note user-specified crashkernel value will be overwritten by default value

    Resolves: https://issues.redhat.com/browse/RHEL-69568

    When kdump-utils gets updated automatically i.e. not updated manually by
    user, users won't notice custom crashkernel value gets overwritten as
    the logs in /var/log/dnf.rpm.log may be ignored,
        2024-12-10T02:57:12-0500 INFO kdump: For kernel=/boot/vmlinuz-6.11.0-28.el10.x86_64, crashkernel=1G-4G:192M,4G-64G:256M,64G-:512M now. Please reboot the system for the change to take effect. Note if you don't want kexec-tools to manage the crashkernel kernel parameter, please set auto_reset_crashkernel=no in /etc/kdump.conf.

    So add a note to kdump.conf.
