96 echo "$PN - wrapper around debootstrap for installing Debian
102 -m, --mirror <URL> Mirror which should be used for apt-get/aptitude.
103 -i, --iso <mnt> Mountpoint where a Debian ISO is mounted to, for use
104 instead of fetching packages from a mirror.
105 -r, --release <name> Release of new Debian system (default: bullseye).
106 -t, --target <target> Target partition (/dev/...) or directory where the
107 system should be installed to.
108 -p, --mntpoint <mnt> Mountpoint used for mounting the target system,
109 has no effect if -t is given and represents a directory.
110 --debopt <params> Extra parameters passed to the debootstrap command.
111 --interactive Use interactive mode (frontend).
112 --nodebootstrap Skip debootstrap, only do configuration to the target.
113 --grub <device> Target for grub installation. Usage example: /dev/sda
114 --efi <device> Target for EFI installation. Usage example: /dev/sda1
115 --arch <arch> Set target architecture, use for installing i386 on amd64.
116 --filesystem <fs> Filesystem that should be used when target is a partition
117 or Virtual Machine (see --vmfile).
118 --force Do not prompt for user acknowledgement.
120 Options for Virtual Machine deployment:
122 --vm Set up a Virtual Machine on an existing block device
123 instead of plainly installing to a partition or
124 directory. Needs to be combined with --target.
125 Example: --vm --target /dev/mapper/your-vm-disk
126 --vmfile Like --vm, but install into a regular file (created by
127 'qemu-img create -f raw ...') instead.
128 Example: --vmfile --target /mnt/sda1/qemu.img
129 --vmsize <size> Use specified size for size of VM file (default: 2G).
130 Syntax as supported by qemu-img, like: --vmsize 3G
131 --vmefi Create an EFI boot partition for the VM.
133 Configuration options:
135 -c, --config <file> Use specified configuration file, defaults to
136 /etc/debootstrap/config
137 -d, --confdir <path> Place of config files for debootstrap, defaults
139 --packages <file> Install packages defined in specified list file
140 instead of using /etc/debootstrap/packages.
141 --nopackages Skip installation of packages defined in
142 /etc/debootstrap/packages
143 --nokernel Skip installation of default kernel images.
144 --nointerfaces Do not copy /etc/network/interfaces from host system
146 (This option is automatically enabled when using --vmfile.)
147 --defaultinterfaces Install a default /etc/network/interfaces file (enabling
148 DHCP for eth0) instead of taking over config from host system.
149 --debconf <file> Pre-seed packages using specified pre-seed db file.
150 --grmlrepos Enable Grml's Debian repository (deb.grml.org).
151 --backportrepos Enable Debian's backports repository (backports.debian.org).
152 --keep_src_list Do not overwrite user provided apt sources.list.
153 --contrib Enable 'contrib' in COMPONENTS (defaults to 'main' only).
154 --non-free Enable non-free / non-free-firmware in COMPONENTS (defaults to 'main' only).
155 --hostname <name> Hostname of Debian system.
156 --nopassword Do not prompt for the root password.
157 --password <pwd> Use specified password as password for user root.
158 --sshcopyauth Use ${HOME}/.ssh/authorized_keys to authorise root login on the target system.
159 --sshcopyid Use locally available public keys to authorise root login on the target system.
160 --bootappend <line> Add specified appendline to kernel whilst booting.
161 --chroot-scripts <d> Execute chroot scripts from specified directory.
162 --pre-scripts <dir> Execute scripts from specified directory (before chroot-scripts).
163 --scripts <dir> Execute scripts from specified directory (after chroot-scripts).
164 --remove-configs Delete grml-debootstrap configuration files from installed system.
168 -v, --verbose Increase verbosity.
169 --debug Execute in very verbose way.
170 -h, --help Print this usage information and exit.
171 -V, --version Show summary of options and exit.
173 Usage examples can be found in the grml-debootstrap manpage.
