This update for transactional-update fixes the following issue:

- Mount efivarfs on EFI systems. (bsc#1162320)

If the EFI variables are not available, some incorrect parameters will be attached to grub2-install,
writing the binary to a wrong location. Due to this, the system fails at reboot with a missing symbol error.
