Description Marko Myllynen 2021-12-07 10:36:54 UTC

Description of problem:
dracut allows updating the standard initramfs image for all kernels with:

dracut -f --regenerate-all

Currently "kdumpctl rebuild" can be used to update the kdump.img image only for the running kernel.

It would be helpful in some cases if "kdumpctl rebuild" would provide similar functionality as dracut so to allow creating/updating the kdump.img for all the installed kernel versions.

For instance, when creating a base image this could be used to create the kdump.img during image creation time thus hopefully avoiding the need for each instance creating the kdump.img after the initial boot.

Version-Release number of selected component (if applicable):
RHEL 8.5

Comment 10 Philipp Rudo 2023-06-19 12:45:20 UTC

Draft for this feature was sent to the mailing list [1]. It became a rather large change so I'm afraid I won't be able to backport it to 8.9/9.3 in time. So deferring this RFE once more.
