And you don't have to remove the previous kernel at all. The kernel packages are multi-versioned, and you can choose the right one to boot via GRUB menu.

On the live CD a boot menu looks as menuentry "openSUSE Leap 15.6 KDE Live" --class os --unrestricted { set gfxpayload=keep echo Loading kernel... linux ($root)/boot/x86_64/loader/linux ${extra_cmdline} ${isoboot} splash=silent quiet systemd.show_status=yes root=live:CDLABEL=openSUSE_Leap_15.6_KDE_Live rd.live.image rd.live.overlay.persistent rd.live.overlay.cowfs=ext4 echo Loading initrd... initrd ($root)/boot/x86_64/loader/initrd } The file system is organized by overlays, one read-only and one writable (see https://documentation.suse.com/appliance/kiwi-9/html/kiwi/building-types.htm... for details) The new kernel is installed in the writable overlay, which is not accessible when booting Grub. Grub starts a base Linux kernel from ($root)/boot/x86_64/loader/linux, which mounts the overlays and somehow transfers control to the installed kernel, which is not the new kernel, although vmlinuz points to it. The configuration to select the new kernel is currently unknown to me. -- You are receiving this mail because: You are on the CC list for the bug.
