[IMPORTANT]
By default a compatible master boot record (MBR) is installed on the device
-(being for example /dev/sdb when executing 'grml2usb grml.iso /dev/sdb1')
+(being for example /dev/sdx when executing 'grml2usb grml.iso /dev/sdx1')
and grub is being used as default bootloader. Avoid installation of the
default MBR using the --skip-mbr option or if you encounter any problems
with the default MBR consider using --syslinux-mbr instead. If bootloader

Troubleshooting and Pitfalls when booting
FAT16 (partition type 6) when using a ext3 filesystem on the partition but
instead use the correct partition type ('83' - Linux) then.
+grub-install complains about /sbin/grub-install and/or xfs_freeze?!
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following message:
+
+ You shouldn't call /sbin/grub-install. Please call /usr/sbin/grub-install instead!
+ xfs_freeze: specified file ["/tmp/tmpqaBK6z/boot/grub"] is not on an XFS filesystem
+
+... is "normal". grub-install sends those messages to stderr. To avoid hiding any
+possible real error messages grml2usb doesn't ignore those messages.
+
Why do I have to use a FAT16 filesystem?
