-What's the difference between grml2hd and grml2usb?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-grml2hd installs a running grml system to a harddisk. When rebooting the
-harddisk installation can be modified and changes will find their way to the
-harddisk immediately. grml2usb copies just the compressed chroot filesystem
-(being the squashfs file), some further informational files and a bootloader to
-your device. This way you don't need as much space as with a harddisk
-installation (just a USB device with >=ISO size) and when rebooting the system
-your changes will be lost (unless you are using the persistency feature, see
-link:http://wiki.grml.org/doku.php?id=persistency[http://wiki.grml.org/doku.php?id=persistency]).
-Think of using a better CD version: booting is (usually) faster, you don't need
-to burn a new CD when a new ISO version arrives (just install the new ISO using
-grml2usb) and you can carry additional files on a writable medium with yourself.
+[NOTE]
+It is *NOT* enough to have just the grml2usb script itself without the according
+files provided either via the Debian package, the git tree or the file
+grml2usb.tgz.
+
+[[dd]]
+Why can't I just dd the ISO to a USB device?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Well, you can. :) Starting with Grml 2009.10 the ISOs are dd-able straight out-of-the-box.
+
+[IMPORTANT]
+Note that ANY existing data on your USB device will be destroyed when
+using the dd approach.

+///////////////////////////////////////////////////////////////////////////////////////////////////
+Grab a recent Grml ISO and use
+link:http://syslinux.zytor.com/wiki/index.php/Doc/isolinux#HYBRID_CD-ROM.2FHARD_DISK_MODE[isohybrid
+from the syslinux project]:
+
+ % isohybrid grml_2009.10.iso
+///////////////////////////////////////////////////////////////////////////////////////////////////
+
+This allows you to dd the Grml ISO to your USB device (use for example
+link:http://www.chrysocome.net/rawwrite[rawwrite] if you've just a Windows
+system available) running:
+
+ % dd if=grml_2013.01.iso of=/dev/sdX
+
+where /dev/sdX is your USB device. Of course this doesn't provide such a
+flexible system like with grml2usb (no multi-ISO setup, no additional default
+bootoptions,...) but it's a nice way to get a working USB boot setup if you
+don't have grml2usb available.
