*-v*, *--verbose*::
Increase verbosity.
+*--vmfile*::
+ Set up a Virtual Machine instead of installing to a partition or directory.
+ This allows deployment of a Virtual Machine. The options needs to be
+ combined with the --target option.
+ Usage example: --vmfile --target /mnt/sda1/qemu.img
+
+*--vmsize* <_size_>::
+ Use specified size for size of Virtual Machine disk file. If not specified it
+ defaults to 2G (being 2GB). Syntax as supported by qemu-img (see manpage
+ qemu-img(1) for details.
+ Usage example: --vmsize 3G
+
*-V*, *--version*::
Show version of program and exit.
grml-debootstrap --target /dev/sda3 --grub /dev/sda --mirror ftp://ftp.tugraz.at/mirror/debian
+Install default debian release (stable/squeeze) in a Virtual Machine file with
+3GB disk size (including Grub as bootmanager in MBR of the virtual disk file):
+
+ mount /dev/sda1 /mnt/sda1
+ grml-debootstrap --vmfile --vmsize 3G --target /mnt/sda1/qemu.img
+
Install default Debian release (stable/squeeze) on /dev/sda3 and install bootmanager
Grub in MBR (master boot record) of /dev/sda and use /dev/sda3 as system partition.
Use specified mirror instead of the default (ftp://ftp.debian.de/debian) one.
