Introduction
------------
-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).

-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).
+ISO[s] should be the path to one or multiple grml-ISOs and/or the path to

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

*\--fat16*::
Remove specified bootoption (could be a regex) from existing boot options. Use
multiple entries for removing different bootoptions at once.
+ *\--skip-bootflag*::
+
+Do not check for presence of bootflag on target device.
+
*\--skip-grub-config*::
Skip generation of grub configuration files. By default the configuration
files for syslinux *and* grub will be written so you've a working configuration
file no matter whether you're using grub or syslinux as bootloader.
+ *\--skip-usb-check*::
+
+Skip check to verify whether given device is a removable device.
+Some USB devices are known to report wrong information, when using
+such a device you can skip grml2usb's removable device check.

This option is deprecated and is being left only for backwards compatibility

files provided either via the Debian package, the git tree or the file
grml2usb.tgz.
-[[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.

Note that ANY existing data on your USB device will be destroyed when
using the dd approach.

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_2009.10.iso of=/dev/sdX
+ % dd if=grml64-full_2018.12.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
