Add kdump dracut config Resolves: RHEL-49590 Upstream: https://github.com/rhkdump/kdump-utils Conflict: Yes, kexec-tools is split into 3 parts upstream, some changes should be applied to kdump-utils Makefile, but RHEL-9 kexec-tools doesn't have that. Also missing upstream commits: - 1732a3b(mkdumprd: Omit rdma module) - 7fec2f56(mkdumprd: simplify handling of dracut arguments) commit dacb34341113fa925c15e28a7ce56a80dd370e2f Author: Lichen Liu <lichliu@redhat.com> Date: Tue Nov 5 12:07:42 2024 +0800 Add kdump dracut config In some cases, customizing the first kernel's initrd is necessary by modifying the dracut `omit_dracutmodules` options, such as in Bootc or CoreOS scenarios [1]. However, these changes can unintentionally break existing functionality in kdump. For instance, setting `omit_dracutmodules='nfs'` prevents the `nfs` module from being added. Additionally, some dracut configurations [2] use `dracutmodules+='some modules'` instead of `add_dracutmodules+='some modules'`. When `dracutmodules` is non-empty, dracut includes only the specified modules, which can result in an initrd that lacks necessary modules, causing kdump to fail. Dracut upstream support --add-confdir now, kdump can use this option when building kdump initramfs. This patch moved the hardcoded dracutmodules from mkdumprd to the new conf file /lib/kdump/dracut.conf.d/99-kdump.conf, it is easier to check and modify to omit or add certain modules. This patch also initialize dracutmodules to empty to avoid the influence of other configurations.
