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