Hi Thomas,

I tried to make a minimal grub iso file, but failed. After installing xorriso too, I had the following error:

$ sudo grub-mkrescue -o output.iso minimal
grub-mkrescue: error: `mformat` invocation failed
.

I tried in an Ubuntu Groovy system. What is mformat? What should I add to make it work? Or would it be easy for you to upload a minimal iso somewhere, so that we (Leo and I) can download and test it?
