My patch proposes a method of setting the > top-level menu entry while this method only sets the default entry, > which may be hidden behind a submenu. I think this can be done already today. At least YaST offers a way to select a specific item in a submenu and pass it to grub-set-default. This leads to an entry like this in grubenv: saved_entry=Advanced options for SLE15SP4 (with Xen hypervisor)>Xen hypervisor, version 4.17.20220823T122205.399bcbf2-xen_unstable.150400.370>SLE15SP4, with Xen 4.17.20220823T122205.399bcbf2-xen_unstable.150400.370 and Linux 5.14.21-150400.24.21-default This entry will be booted as long as both this specific Xen version and this specific kernel version is found. There is a slim chance a SUSE specific patch exists to enable this functionality. Maybe the patch description lacks a specific example how the proposed change is supposed to be used in your environment. Olaf
