Dear Maintainer,
Please add gparted to list of packages in non-free firmware.iso . To
see if gparted was available, looked at
https://cdimage.debian.org/cdimage/unofficial/non-free/images-including-firmware/9.6.0-live+nonfree/amd64/iso-hybrid/debian-live-9.6.0-amd64-mate+nonfree.iso
as well as https://cdimage.debian.org/cdimage/unofficial/non-free/images-including-firmware/9.6.0-live+nonfree/amd64/iso-hybrid/debian-live-9.6.0-amd64-mate+nonfree.packages
and couldn't find gparted listed in there.
