• Description of the issue (ideally so that others can reproduce it):
  Attempting to increase the EFI partition created from running "rear format -- --efi /dev/sdb will on create a 200Mib partition.
  Attempt to edit the value set here: test "$USB_UEFI_PART_SIZE" || USB_UEFI_PART_SIZE="1024" in the /usr/share/rear/format/USB/default/300_format_usb_disk.sh file still results in a 200MB partition.

• Workaround, if any: Not yet. Any tips or tricks would be much appreciated.

• Attachments, as applicable ("rear -D mkrescue/mkbackup/recover" debug log files):

I thought i had searched for this "USB_UEFI_PART_SIZE="200"" in the /usr/share/rear/conf/default.conf. However, it turns out I did not. Just changed the value in the default.conf file and reformatted the USB device and got a 1G partition.
