Comment # 7 on bug 1226676 from Jiri Bohac

By default kdump relies on the /boot/vmlinuz symlink (or other image name
variants  on non-x86 archs). This points to the last installeed kernel.
When a specific kernel version is requested by setting KDUMP_KERNELVER=xxx then
it relies on the /boot/vmlinuz-xxx symlink.

These links have always been created by the
kernel's %post scriplet, which calls
/usr/lib/module-init-tools/kernel-scriptlets/rpm-post

This script used to be provided by the suse-module-tools-scriptlets subpackage.
This is where the links are created: 
https://github.com/openSUSE/suse-module-tools/blob/790fe7ce0eb9db37932c65161d88da73efcb809f/kernel-scriptlets/rpm-script#L183

When I installe with sdboot, sdbootutil-rpm-scriptlets is installed instead of
suse-module-tools-scriptlets and no such symlinks are created.

One way of fixing this would be to create the symlinks in
sdbootutil-rpm-scriptlets.

Another way would be for kdump to look for the kernels elsewhere.

To me the post scriplet seems to be an ideal place to deal with this, without
kdump having to embed knowledge of the location of kernel images which could be
fragile.

Could the links be added to sdbootutil-rpm-scriptlets?
