Can you either post the entire grub.cfg, or you can also edit an older entry and check what root= it uses. For any rootfs on LVM, I expect root=/dev/mapper/VG-LV. When updating the kernel, it calls grubby, which should just create a new entry based on a previous entry only updating the name of the kernel and initramfs accordingly. I haven't seen it change the root entry. > > The other thing you can do is create a new grub.cfg from scratch by using > > grub2-mkconfig -o /boot/grub2/grub.cfg > > This is the same command the installer used when Fedora was installed. > Thank you for the information. When I run grub2-mkconfig -o /boot/grub2/grub.cfg.test the generated file is correct. I am not able to reproduce manually what happens during the 2 last kernal updates. I will check again after the next update. =========================================================================== Patrick DUPRÉ | | email: pdupre@xxxxxxx Laboratoire de Physico-Chimie de l'Atmosphère | | Université du Littoral-Côte d'Opale | | Tel.
