So all works fine but the grub2 menu entry promises a opensuse 12.3? How can i change it? I simply want to change the entry text. It should inform the user that a 13.1 system will start…
Change the “Distributor” string in YaST->System->Boot Loader->Boot Loader Options, or edit /etc/default/grub manually with a text-editor (and call grub2-mkconfig afterwards to recreate the menu, as mentioned in that file).
Btw, openSUSE 13.2 uses just “openSUSE” by default, to avoid this “problem” for future upgrades.
