+grml2usb installs Grml on a given partition of your usb device and makes it
+bootable. It provides multi-iso support, meaning you can specify several Grml
+ISOs on the command line at once and select the Grml flavour you would like to
boot on the bootprompt then. Note that the *first* ISO specified on the grml2usb
command line will become the default one (that's the one that will boot when
just pressing enter on the bootprompt or wait until the boot timeout matches).
Options

-The ISO[s] should be the path to one or multiple grml-ISOs and/or the path to
-the currently running live-system (being /live/image).

The device either might be a device name like /dev/sdX1 or a directory. When
specifying a device name the device is mounted automatically. When specifying a

-[[grml2hd-vs-grml2usb]]
-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.
-
[[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.
