What's the difference between grml2hd and grml2usb?

installation (just a USB device with >=ISO size) and when rebooting the system

Why is there a menu.lst and a grub.cfg inside /boot/grub/?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
... is "normal". grub-install sends those messages to stderr. To avoid hiding any
possible real error messages grml2usb doesn't ignore those messages.
+grub-install complains about /boot/grub/device.map?!
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following message:
+
+ grub-probe: error: Cannot open `/boot/grub/device.map'
+
+... is "normal" (at least with grub1). This isn't a problem, because the
+device.map file will be generated on the target device anyway.
+
+grub-install complains about a unary operator?!
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following message:
+
+ '/usr/sbin/grub-install: line 374: [: =: unary operator expected'
+
+... is "normal". Just ignore it.

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

Why do I have to use a FAT16 filesystem?

+You have to use a FAT16 filesystem only if you consider using syslinux. Syslinux
(currently) does not support any other filesystems. If you want to use another
filesystem (like ext2/3) just don't use syslinux (drop the \--syslinux option)
but use the default bootloader (grub) instead.
