+Subject: [PATCH] grub-switch-to-blscfg: Update grub2 binary in ESP for OSTree
+ systems
+
+The grub2 EFI binary in the ESP isn't updated as a part of an OSTree update
+transaction. So let's make the script to update this and also create a file
+to indicate that the installed version has support for the blscfg module.
