+ 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
+
+This is "normal". grub-install sends those messages to stderr. To avoid hiding any
+possible real error messages grml2usb doesn't ignore those messages.
+
+[[device-map]]
+grub-install complains about /boot/grub/device.map?!
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following message:
+
+ grub-probe: error: Cannot open `/boot/grub/device.map'
+
+This is "normal" (at least with grub1). This isn't a problem, because the
+device.map file will be generated on the target device anyway.
+
+[[unary-operator]]
+grub-install complains about a unary operator?!
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following message:
+
+ '/usr/sbin/grub-install: line 374: [: =: unary operator expected'
+
+This is "normal". Just ignore it. (It usually doesn't appear
+on the second invocation on the same device.)
+
+[[unknown-filesystem]]
+grub-install fails with grub-probe: error: unknown filesystem?!
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following message:
+
+ grub-probe: error: unknown filesystem
+ Auto-detection of a filesystem module failed.
+ Please specify the module with the option `--modules' explicitly.
+
+usually means that the device partition table says something else than the
+filesystem on the device. For example using FAT16 as filesystem type and
+using FAT32 as filesystem on the partition will not work. Either set filesystem
+type to FAT32 or format the partition using FAT16. It is essential that
+device partition table and filesystem use the same filesystem type.
+
+[[mbr-vs-pbr]]
+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 when using grub2 versions older than 1.98 as those version introduced a
+regression which avoids that grub is being installed into a partition (PBR,
+Partition Boot Record) instead of MBR (Master Boot Record).
+
+To work around this issue you can either 1) upgrade to grub versions >=1.98, 2)
+install grub into the MBR (Master Boot Record) using the '--grub-mbr' option of
+grml2usb or 3) switch to syslinux as bootmanager (just drop the '--grub'
+option).
+
+[[splash-xpm]]
+I'm getting something like "Error: /usr/share/grml2usb/grub/splash.xpm.gz can not be read"!?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Looks like you've only the grml2usb script itself available. Please make sure
+you've the grml2usb Debian package installed. The most resent stable version is
+available via link:http://deb.grml.org/[the grml-testing Debian repository]. If
+you do not have a Debian system please see section <<download,Where can I get
+grml2usb?>> in this FAQ.
+
+[[fat16]]
+Why do I have to use a FAT16/FAT32 filesystem?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Syslinux (currently) does not support any other filesystems besides FAT16/FAT32
+(though that's a sane default if you want to share your files with other
+(operating) systems). If you want to use a different filesystem (like ext2/3)
+use the bootloader grub instead using grml2usb's '--grub' option.
+
+[NOTE]
+FAT32 is supported since syslinux version 3.0.
