Grabbing the source
~~~~~~~~~~~~~~~~~~~

+ % git clone git://git.grml.org/grml2usb.git
Developers Debugging Hints
~~~~~~~~~~~~~~~~~~~~~~~~~~
To play with grml2usb you can avoid using a real device via a loopback file
setup, like:
- dd if=/dev/zero of=~/loopback bs=1M count=100 # adjust size to your needs
- losetup /dev/loop1 ~/loopback
+ # dd if=/dev/zero of=~/loopback bs=1M count=100 # adjust size to your needs
+ # losetup /dev/loop1 ~/loopback
Then create according partitions either running for example:
- echo -en "n\np\n1\n\n\n t \n 6\n a\n1\n w\n" | fdisk /dev/loop1
+ # echo -en "n\np\n1\n\n\nt\n6\na\n1\n w\n" | fdisk /dev/loop1
or:
- parted /dev/loop1 -s "mkpart primary fat16 0 -1s mkfs 1 fat16"
+ # parted /dev/loop1 -s "mkpart primary fat16 0 -1s mkfs 1 fat16"
Finally create a filesystem and execute grml2usb as needed:
- mkfs.vfat /dev/loop1
- grml2usb --bootloader-only --mbr /grml/isos/grml-small_2008.11.iso /dev/loop1
+ # mkfs.vfat /dev/loop1
+ # grml2usb --bootloader-only /grml/isos/grml-small_2008.11.iso /dev/loop1
+
+Performance tracing
+~~~~~~~~~~~~~~~~~~~
+
+ # blktrace -d /dev/sdb -o - | blkparse -i -
+ # grml2usb grml_2008.11.iso /dev/sdb1
Frequently Asked Questions (FAQ)

You have to use a FAT16 filesystem if you consider using syslinux (being the
-default when using the --mbr option). Syslinux currently does not support any

-using the --grub option instead.
