+Subject: [PATCH] grub-install: remove useless check PReP partition is empty.
+
+References: bsc#1065738
+
+The grub-install rewrite in commit cd46aa6cefab checks that the PPeP
+partition does not install an ELF binary before writing grub to it. This
+causes regression in installer scripts that expect to be able to
+reinstall bootloaders without first witping the partition by hand.
+
+Fixes: cd46aa6cefab ("Rewrite grub-install, grub-mkrescue,
+    grub-mkstandalone and grub-mknetdir ")
