 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
