[Xen-devel] [PATCH v2 1/2] 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

        }
 }

 ### 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.
