Hi, all, I'd think that grub2 and grub2-efi should be marked as conflict with each other 'cause 1) They put some common scripts into /etc/grub.d and /sbin with same names although some grub2-efi scripts start with prefix 'grub2-efi'. 2) Remove either grub2 or grub2-efi would affect another. Another little bug about grub2-efi: Some scripts from grub2-efi take wrong sed regex when transforming commands, eg. /etc/grub.d/00_header. When I try to execute 'grub2-efi-mkconfig -o /boot/grub2-efi/grub.cfg', '00_header' from grub2-efi would transform 'grub-*' commands to 'grub2-*' rather than 'grub2-efi-*'.
