Hi,

sorry for the late reply. I just took a closer look at your bug report.

We're using "/boot/grml32full" instead of "/boot/grml32-full" because isolinux has problems with 
'-' inside the directory name. :(

The "grml32-full" as used inside live-media-path is directly coming from the Grml version string, 
using 'grml32full' is sadly not really an option from my PoV.

The easiest solution for your GRUB template should be just assigning two variables, like:

  set grmlversion="grml32-full"
  set kerneldir="grml32full"

If there are better options we'd be happy to hear them. :)

regards,
Mika
