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 bootbrompt then. Note that the *first* ISO specified on the grml2usb
+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).
[IMPORTANT]
By default a compatible master boot record (MBR) is installed on the device
-(being for example /dev/sdx when executing 'grml2usb grml.iso /dev/sdx1')
-and grub is being used as default bootloader. Avoid installation of the
-default MBR using the --skip-mbr option or if you encounter any problems
-with the default MBR consider using --syslinux-mbr instead. If bootloader
-grub doesn't work for you check out the --syslinux option.

+[NOTE]

+script grml2usb-compat supports older grml releases (<2009.10) as well.

Frequently Asked Questions (FAQ)
--------------------------------
+[[download]]
+Where can I get grml2usb?
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+grml2usb is available as Debian package via link:http://deb.grml.org/[the
+grml-testing Debian repository].
+
+If you do not want to (or can't) use the grml2usb Debian package you can either
+use the grml2usb git tree running:
+
+ git clone git://git.grml.org/grml2usb.git
+ cd grml2usb
+ make -C mbr
+ sudo ./grml2usb ...
+
+or download the provided
+link:http://grml.org/grml2usb/grml2usb.tgz[http://grml.org/grml2usb/grml2usb.tgz]
+(link:http://grml.org/grml2usb/grml2usb.tgz.md5.asc[gpg signed md5 hash]).
+Download and extract the tarball and execute the provided script 'install.sh'.
+
+[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.

+[[grml2hd-vs-grml2usb]]
What's the difference between grml2hd and grml2usb?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
(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 (even though a persistent root feature is
-work-in-progress). 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

+
+[[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_2009.10.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.
+
+[[grml2usb-vs-dd]]
+What's the difference between grml2usb and just using dd?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+grml2usb does not remove any data from your USB device and does not alter the
+partition table at all. grml2usb provides multi-ISO support, support for adding
+default bootoptions and selecting the bootloader (syslinux vs. grub) without
+having to manually touch the ISO at all.
+
+[[grml2iso]]
+What's grml2iso?
+~~~~~~~~~~~~~~~~
+
+grml2iso is a script which uses grml2usb to generate a multiboot ISO out of
+several grml ISOs. See 'man grml2iso' for further details.
+
+[[grml2usb-compat]]
+grml2usb fails with "Fatal: file default.cfg could not be found."
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you are trying to install an older grml ISO (older than grml 2009.10) with a
+recent version of grml2usb then you might notice:
+
+ Fatal: file default.cfg could not be found.
+ Note: this grml2usb version requires an ISO generated by grml-live >=0.9.24 ...
+ ... either use grml releases >=2009.10 or switch to an older grml2usb version.
+ Please visit http://grml.org/grml2usb/#grml2usb-compat for further information
+ Fatal: a critical error happend during execution (not a grml ISO?), giving up
+
+Breaking the backward compatibility was necessary to avoid maintainability hell.
+If you want to install older grml ISOs please use the grml2usb-compat script
+which provides support for older releases.
+
+[[menu-lst]]
Why is there a menu.lst and a grub.cfg inside /boot/grub/?

+[[device-map]]
+grub-install complains about /boot/grub/device.map?!
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The following message:
-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.
+ 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 because recent grub2 versions sadly 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 install grub into the MBR (Master Boot Record)
+using the '--grub-mbr' option of grml2usb or switch to syslinux as bootmanager
+(just drop the '--grub' option).
+
+To fix this issue manually you can also execute (adjust '/dev/sdX' to your
+device of course):
+
+ mount /dev/sdX1 /mnt/test
+ grub-install --force --recheck --no-floppy --root-directory=/mnt/test /dev/sdX
+
+[[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.
