Commit d33045ce7ffcb7c1e4a60c14d5ca64b36e3c5abe introduced the support for this, but it does not work under x86 (as it stops 20_linux_xen from running). The 20_linux_xen is run under a shell and any exits from within it: (For example on x86): + /usr/bin/grub2-file --is-arm64-efi /boot/xen-4.9.0.gz [root@tst063 grub]# echo $? 1 will result in 20_linux_xen exiting without continuing and also causing grub2-mkconfig to stop processing. As in: [root@tst063 grub]# ./grub-mkconfig | tail Generating grub configuration file ... Found linux image: /boot/vmlinuz-4.13.0-0.rc5.git1.1.fc27.x86_64 Found initrd image: /boot/initramfs-4.13.0-0.rc5.git1.1.fc27.x86_64.img Found linux image: /boot/vmlinuz-0-rescue-ec082ee24aea41b9b16aca52a6d10cc2 Found initrd image: /boot/initramfs-0-rescue-ec082ee24aea41b9b16aca52a6d10cc2.img echo 'Loading Linux 0-rescue-ec082ee24aea41b9b16aca52a6d10cc2 ...' linux /vmlinuz-0-rescue-ec082ee24aea41b9b16aca52a6d10cc2 root=/dev/mapper/fedora_tst063-root ro single echo 'Loading initial ramdisk ...' initrd /initramfs-0-rescue-ec082ee24aea41b9b16aca52a6d10cc2.img } } ### END /usr/local/etc/grub.d/10_linux ### ### BEGIN /usr/local/etc/grub.d/20_linux_xen ### root@tst063 grub]# And no more. This patch wraps the invocation of grub-file to be a in subshell and to process the return value in a conditional. That fixes the issue.
