NAME

       debootstrap - Bootstrap a basic Debian system

SYNOPSIS

       debootstrap [OPTION...]  SUITE TARGET [MIRROR [SCRIPT]]

       debootstrap [OPTION...]  --second-stage

DESCRIPTION

       debootstrap  bootstraps  a basic Debian system of SUITE into TARGET from MIRROR by running
       SCRIPT.  MIRROR can be an http:// or https:// URL, a file:/// URL, or an ssh:/// URL.

       The SUITE may be a release code name (eg, sid, jessie, wheezy) or  a  symbolic  name  (eg,
       unstable, testing, stable, oldstable)

       Notice that file:/ URLs are translated to file:/// (correct scheme as described in RFC1738
       for local filenames), and file:// will not work.  ssh://USER@HOST/PATH URLs are  retrieved
       using scp; use of ssh-agent or similar is strongly recommended.

       Debootstrap  can  be used to install Debian in a system without using an installation disk
       but can also be used to run a different Debian flavor in a chroot environment.   This  way
       you can create a full (minimal) Debian installation which can be used for testing purposes
       (see the EXAMPLES section).  If you are looking for a  chroot  system  to  build  packages
       please take a look at pbuilder.

OPTIONS

       --arch=ARCH
              Set the target architecture (use if dpkg isn't installed).  See also --foreign.

       --include=alpha,beta
              Comma separated list of packages which will be added to download and extract lists.

       --exclude=alpha,beta
              Comma  separated  list  of packages which will be removed from download and extract
              lists.  WARNING: you can and probably will exclude essential packages,  be  careful
              using this option.

       --components=alpha,beta
              Use packages from the listed components of the archive.

       --no-resolve-deps
              By   default,  debootstrap  will  attempt  to  automatically  resolve  any  missing
              dependencies, warning if  any  are  found.   Note  that  this  is  not  a  complete
              dependency  resolve  in  the  sense  of  dpkg  or apt, and that it is far better to
              specify the entire base system than rely on this option.   With  this  option  set,
              this behaviour is disabled.

       --variant=minbase|buildd|fakechroot|scratchbox
              Name of the bootstrap script variant to use.  Currently, the variants supported are
              minbase, which only includes essential packages and apt; buildd, which installs the
              build-essential  packages  into TARGET; and fakechroot, which installs the packages
              without root privileges.   Finally  there  is  variant  scratchbox,  which  is  for
              creating  targets for scratchbox usage.  The default, with no --variant=X argument,
              is to create a base Debian installation in TARGET.

       --keyring=KEYRING
              Override the default keyring for  the  distribution  being  bootstrapped,  and  use
              KEYRING to check signatures of retrieved Release files.

       --no-check-gpg
              Disables checking gpg signatures of retrieved Release files.

       --force-check-gpg
              Forces  checking  Release file signatures, disabling automatic fallback to HTTPS in
              case of a missing keyring. Incompatible with the previous option.

       --verbose
              Produce more info about downloading.

       --print-debs
              Print the packages to be installed, and exit.  Note that a TARGET directory must be
              specified  so  debootstrap  can download Packages files to determine which packages
              should be installed, and to resolve dependencies.  The  TARGET  directory  will  be
              deleted unless --keep-debootstrap-dir is specified.

       --download-only
              Download packages, but don't perform installation.

       --foreign
              Do  the  initial  unpack  phase  of  bootstrapping  only, for example if the target
              architecture  does  not  match  the  host  architecture.   A  copy  of  debootstrap
              sufficient   for   completing   the   bootstrap   process   will  be  installed  as
              /debootstrap/debootstrap in the  target  filesystem.   You  can  run  it  with  the
              --second-stage option to complete the bootstrapping process.

       --second-stage
              Complete the bootstrapping process.  Other arguments are generally not needed.

       --second-stage-target=DIR
              Run  second  stage  in  a  subdirectory  instead  of root. (can be used to create a
              foreign chroot) (requires --second-stage)

       --keep-debootstrap-dir
              Don't delete  the  /debootstrap  directory  in  the  target  after  completing  the
              installation.

       --unpack-tarball=FILE
              Acquire .debs from tarball FILE instead of downloading via http.

       --make-tarball=FILE
              Instead  of  bootstrapping,  make  a  tarball  (written  to FILE) of the downloaded
              packages.  The resulting tarball may be passed to a later --unpack-tarball.

       --debian-installer
              Used for internal purposes by the debian-installer

       --extractor=TYPE
              Override automatic .deb extractor selection to  TYPE.   Supported  extractors  are:
              dpkg-deb and ar.

       --no-check-certificate
              Do not check certificate against certificate authorities

       --certificate=FILE
              Use the client certificate stored in file (PEM)

       --private-key=FILE
              Read the private key from file

EXAMPLES

       To setup a wheezy system:

            debootstrap wheezy ./wheezy-chroot http://httpredir.debian.org/debian

            debootstrap wheezy ./wheezy-chroot file:///LOCAL_MIRROR/debian

       Full process to create a complete Debian installation of sid (unstable) in a chroot:

            main # debootstrap sid sid-root http://httpredir.debian.org/debian/
            [ ... watch it download the whole system ]
            main # echo "proc sid-root/proc proc defaults 0 0" >> /etc/fstab
            main # mount proc sid-root/proc -t proc
            main # echo "sysfs sid-root/sys sysfs defaults 0 0" >> /etc/fstab
            main # mount sysfs sid-root/sys -t sysfs
            main # cp /etc/hosts sid-root/etc/hosts
            main # chroot sid-root /bin/bash
