With 3 distro installations on one disk, each OS as a kernel update is installed updates NVRAM to make its entry in the ESP partition top priority. How can I stop that from happening, so that my choice of priority remains first instead of me needing to remember before shutdown or reboot to run efibootmgr to put it back like it was before the kernel update? I don't want to prevent the update from creating a new /boot/grub/grub.cfg, only from usurping boot priority.
In Mageia you can use drakboot (from MCC) and select to "not touch MBR or ESP" in an Advanced screen. This adds switches ( --bootloader-id=tmp --no-nvram) to grub2-install in /boot/grub2/install.sh (which is used during kernel updates) to stop the nvram entries being upset.
It is a hack using a dummy entry, but it works. How or if other distros implement this functionality I have no idea. _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
