+grub-setup fails after Attempting to install GRUB to a partition instead of the MBR?!
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following message:
+
+ grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea.
+ grub-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and its use is discouraged.
+ grub-setup: error: Cannot read `/grub/core.img' correctly
+
+appears because recent grub2 versions introduced a regression which avoids that
+grub is being installed into a partition (instead of MBR). We (the grml2usb
+developers) are evaluating the current situation (thinking about installing grub
+into the MBR). To fix this issue in the meanwhile either manually execute
+(adjust '/dev/sdx' to your device of course):
+
+ mount /dev/sdx1 /mnt/test
+ grub-install --force --recheck --no-floppy --root-directory=/mnt/test /dev/sdx
+
+after execution of grml2usb failed (this will will install grub into the MBR of
+the specified device) or consider using the '--syslinux' option until this issue
+is resolved. Sorry about that.

I'm getting something like "Error: /usr/share/grml2usb/grub/splash.xpm.gz can not be read"!?
