Bug#1081288: systemd-boot: bootctl incorrectly believes that GPT is required for EFI boot

[Russell Coker]

Package: systemd-boot
Version: 256.5-2
Severity: normal

This system booted from EFI:

# ls -l /sys/firmware/efi/
total 0
-r--r--r--. 1 root root 4096 Sep 10 22:40 config_table
drwxr-xr-x. 2 root root    0 Sep 10 22:11 efivars
drwxr-xr-x. 3 root root    0 Sep 10 22:40 esrt
-r--r--r--. 1 root root 4096 Sep 10 22:21 fw_platform_size
-r--r--r--. 1 root root 4096 Sep 10 22:40 fw_vendor
-r--r--r--. 1 root root 4096 Sep 10 22:40 runtime
drwxr-xr-x. 8 root root    0 Sep 10 22:40 runtime-map
-r--------. 1 root root 4096 Sep 10 22:40 systab

bootctl claims that it can't boot EFI because it uses MBR:

# bootctl list --esp-path=/boot/efi
File system "/dev/nvme0n1p1" is not on a GPT partition table.

Windows apparently requries GPT to boot with UEFI but Linux doesn't.
