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
