Option '--bootloader-only' does not make sense with option '--fat16'

[jkirk]

.. or does it?

For me both options should be mutual exclusive:

% sudo ./grml2usb --skip-addons --bootloader-only --fat16 /srv/data/isos/grml64-full_testing_build3133.iso /dev/sdb1
Executing grml2usb version v0.18.0-4-g83e35c2 (git)
Are you sure you want to format the specified partition with fat16? y/N
Note: you can skip this question using the option --force

Fatal: Device /dev/sdb1 does not have the boot flag set. Please enable it to be able to boot.
