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:// 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  --vari-
	      ant=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.

       --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://ftp.us.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://ftp.us.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
