Usage example: /dev/sda --arch Architecture to use. Currently only i386 is supported. --filesystem Filesystem that should be used when target is a partition. --insecure Do not download and check Release file signatures. Configuration options: -c, --config Use specified configuration file, defaults to /etc/debootstrap/config -d, --confdir Place of config files for debootstrap, defaults to /etc/debootstrap --packages Install packages defined in specified list file. --nopackages Skip installation of packages defined in /etc/debootstrap/packages --debconf Pre-seed packages using specified pre-seed db file. --keep_src_list Do not overwrite user provided apt sources.list. --hostname Hostname of Debian system. --password Use specified password as password for user root. --bootappend Add specified appendline to kernel whilst booting. --chroot-scripts Execute chroot scripts from specified directory. --pre-scripts Execute scripts from specified directory (before chroot-scripts). --scripts Execute scripts from specified directory (after chroot-scripts). Other options: -v, --verbose Increase verbosity. -h, --help Print this usage information and exit. -V, --version Show summary of options and exit.
