A different bug that ubuntu-bug will not report. When creating a UEFI bootable USB device, mkusb partition 1 after the GUID Partition Table is the usbdata partition. Partition 2 is a 1 MB wasted space for BIOS booting (it contains the Microsoft boot code that will not fit in the Master Boot Record and is required to be immediately after the MBR.

Since the USB device does not have an MBR and is booted with UEFI, the 1MB partition is totally unnecessary and is a waste of disk space and a waste of an entry in the GUID Partition Table.

When creating a volume with a GUID Partition Table, this BIOS partition should be omitted.
