From a8e0f1adf7019238fff263111794c86f4eea79ac Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Tue, 29 Aug 2017 16:40:52 -0400 Subject: [PATCH] Fix util/grub.d/20_linux_xen.in: Add xen_boot command support for aarch64 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 ...

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. RH-BZ 1486002: grub2-mkconfig does not work if xen.gz is installed.
