This script was planned to be removed from the dracut package because it's not the right place to distribute it. But it seems the new package that should contain it (kernel-install-tools) is not present yet. There are two options: - Wait until kernel-install-tools is available. - Download the script from https://github.com/openSUSE/dracut/blob/SUSE/049/suse/dracut-installkernel and copy it to /sbin/installkernel. The PR discussion can be followed here: https://github.com/openSUSE/dracut/pull/85
