Subject: [PATCH] Only attempt to query dev mounted in /boot/efi as boot dev on
EFI machines
The 10_linux script calls grub2-probe to probe the information for the dev
mounted in /boot/efi, but this directory may not exist on non-EFI machines
which leads to the following error when generating the grub2 config file:
/usr/sbin/grub2-probe: error: failed to get canonical path of `/boot/efi/'
Instead query for the device mounted in /boot and use that as the boot dev
for non-EFI machines.
