kernel efi stub issues

the problem I see for a casual system is that system upgrades won’t change /boot/efi/ but only /boot. leaving the system alone with an older kernel. using yet-another-bootloader (like it is usually done on EFI) solves that.

kernel efi stub doesn’t like qemu+ovmf

autoboot and the efibootmgr -u flag doesn’t work on qemu+ovmf, that’s why syslinux or grub is prefered for KVM guests
