Sorry, my bad; bootctl comes with systemd. I thought it came with gummiboot.

However, "gummiboot status" shows almost the same information. In my case:

Boot Loader Binaries:
          ESP: /dev/disk/by-partuuid/b4abf4dc-abfc-45c5-b356-30db1e0b15b3
         File: └─/EFI/gummiboot/gummibootx64.efi (gummiboot 45)
         File: └─/EFI/Boot/BOOTX64.EFI (gummiboot 45)

Boot Loader Entries in EFI Variables:
        Title: UEFI OS
           ID: 0x0001
       Status: active, boot-order
    Partition: /dev/disk/by-partuuid/b4abf4dc-abfc-45c5-b356-30db1e0b15b3
         File: └─/EFI/BOOT/BOOTX64.EFI

As you can see, Boot/BOOTX64.EFI is actually gummiboot.
