Use specified bootoptions as default.

Do *not* copy files but instead just install a bootloader. Note that the boot
addons are copied to /boot/addons at this stage as well. If you want to skip
copying the boot addons consider using the --skip-addons option.

+ *\--dry-run*::
Avoid executing commands, instead show what would be executed.
Warning: please notice that the ISO has to be mounted anyway, otherwise
identifying the grml flavour would not be possible.
- *--fat16*::
+ *\--fat16*::
Format specified partition with FAT16.
**Important:** this will destroy any existing data on the specified partition!

- *--mbr-menu*::
+ *\--mbr-menu*::
Install master boot record (MBR) with integrated boot menu: interactively choose
the partition to boot from, with a timeout to load the default partition, or
syslinux). Note: This options is available only when using the default MBR and
won't have any effect if you're using the --syslinux-mbr option.

Why is there a menu.lst and a grub.cfg inside /boot/grub/?

possible real error messages grml2usb doesn't ignore those messages.

+
+The following message:

+ grub-probe: error: Cannot open `/boot/grub/device.map'
