echo "$PN - wrapper around debootstrap for installing Debian
Usage: $PN [options]
Bootstrap options:
-m, --mirror <URL> Mirror which should be used for apt-get/aptitude.
-i, --iso <mnt> Mountpoint where a Debian ISO is mounted to, for use
instead of fetching packages from a mirror.
-r, --release <name> Release of new Debian system (default: bullseye).
-t, --target <target> Target partition (/dev/...) or directory where the
system should be installed to.
-p, --mntpoint <mnt> Mountpoint used for mounting the target system,
has no effect if -t is given and represents a directory.
--debopt <params> Extra parameters passed to the debootstrap command.
--interactive Use interactive mode (frontend).
--nodebootstrap Skip debootstrap, only do configuration to the target.
--grub <device> Target for grub installation. Usage example: /dev/sda
--efi <device> Target for EFI installation. Usage example: /dev/sda1
--arch <arch> Set target architecture, use for installing i386 on amd64.
--filesystem <fs> Filesystem that should be used when target is a partition
or Virtual Machine (see --vmfile).
--force Do not prompt for user acknowledgement.
Options for Virtual Machine deployment:
--vm Set up a Virtual Machine on an existing block device
instead of plainly installing to a partition or
directory. Needs to be combined with --target.
Example: --vm --target /dev/mapper/your-vm-disk
--vmfile Like --vm, but install into a regular file (created by
'qemu-img create -f raw ...') instead.
Example: --vmfile --target /mnt/sda1/qemu.img
--vmsize <size> Use specified size for size of VM file (default: 2G).
Syntax as supported by qemu-img, like: --vmsize 3G
Configuration options:
-c, --config <file> Use specified configuration file, defaults to
/etc/debootstrap/config
-d, --confdir <path> Place of config files for debootstrap, defaults
to /etc/debootstrap
--packages <file> Install packages defined in specified list file
instead of using /etc/debootstrap/packages.
--nopackages Skip installation of packages defined in
/etc/debootstrap/packages
--nokernel Skip installation of default kernel images.
--nointerfaces Do not copy /etc/network/interfaces from host system
to target system.
(This option is automatically enabled when using --vmfile.)
--defaultinterfaces Install a default /etc/network/interfaces file (enabling
DHCP for eth0) instead of taking over config from host system.
--debconf <file> Pre-seed packages using specified pre-seed db file.
--grmlrepos Enable Grml's Debian repository (deb.grml.org).
--backportrepos Enable Debian's backports repository (backports.debian.org).
--keep_src_list Do not overwrite user provided apt sources.list.
--contrib Enable 'contrib' in COMPONENTS (defaults to 'main' only).
--non-free Enable non-free / non-free-firmware in COMPONENTS (defaults to 'main' only).
--hostname <name> Hostname of Debian system.
--nopassword Do not prompt for the root password.
--password <pwd> Use specified password as password for user root.
--sshcopyauth Use ${HOME}/.ssh/authorized_keys to authorise root login on the target system.
