Hi martinigm, and thank you very much for your work, and the fact that you put it up for people to download.
I've been trying to integrate Mate into NOOBS, and it was driving me CRAZY!!!! .
I tried to make my own version by following and modifying this https://github.com/raspberrypi/noobs/wiki/Adding-custom-OS-version-examples. After doing everything on the page it would error out when installing. The page is for Noobs 1.5 though.
Then I stumbled upon your post by desperation and LUCK .
Quite simply how did you create the partition_setup.sh file as that is what NOOBS 2.4.1 would always crash on.
I tried to do some research on the partition_setup.sh file but I got nothing that I could understand .
Any pointers on how you created the MATE partition_setup.sh would be greatly appreciated for future custom installs.
Thanks once again.
