.TH DEBOOTSTRAP 8 2001-04-27 "Debian Project" "Debian GNU/Linux manual" .SH NAME debootstrap \- Bootstrap a basic Debian system .SH SYNOPSIS .B debootstrap .RB [ OPTION\&.\&.\&. ] .I SUITE TARGET .RI [ MIRROR .RI [ SCRIPT ]] .B debootstrap .RB [ OPTION\&.\&.\&. ] \-\-second\-stage .SH DESCRIPTION .B debootstrap bootstraps a basic Debian system of .I SUITE into .I TARGET from .I MIRROR by running .IR SCRIPT . .I MIRROR can be an http:// or https:// URL, a file:/// URL, or an ssh:/// URL. .PP The .I SUITE may be a release code name (eg, sid, stretch, jessie) or a symbolic name (eg, unstable, testing, stable, oldstable) .PP Notice that file:/ URLs are translated to file:/// (correct scheme as described in RFC1738 for local filenames), and file:// will \fBnot\fR work. ssh://USER@HOST/PATH URLs are retrieved using .BR scp ; use of .B ssh\-agent or similar is strongly recommended. .PP \fBDebootstrap\fR 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 \fBchroot\fR environment. This way you can create a full (minimal) Debian installation which can be used for testing purposes (see the \fBEXAMPLES\fR section). If you are looking for a chroot system to build packages please take a look at \fBpbuilder\fR. .SH "OPTIONS" .PP .IP "\fB\-\-arch=ARCH\fP" Set the target architecture (use if dpkg isn't installed). See also \-\-foreign. .IP .IP "\fB\-\-include=alpha,beta\fP" Comma separated list of packages which will be added to download and extract lists. .IP .IP "\fB\-\-exclude=alpha,beta\fP" 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. .IP .IP "\fB\-\-components=alpha,beta\fP" Use packages from the listed components of the archive. .IP .IP "\fB\-\-no\-resolve\-deps\fP" 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. .IP .IP "\fB\-\-variant=minbase|buildd|fakechroot\fP" 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 .IR TARGET ; and fakechroot, which installs the packages without root privileges. The default, with no \fB\-\-variant=X\fP argument, is to create a base Debian installation in .IR TARGET . .IP .IP "\fB\-\-merged-usr\fP" Create /{bin,sbin,lib}/ symlinks pointing to their counterparts in /usr/. .IP .IP "\fB\-\-no-merged-usr\fP" Do not create /{bin,sbin,lib}/ symlinks pointing to their counterparts in /usr/. (Default.) .IP .IP "\fB\-\-keyring=KEYRING\fP" Override the default keyring for the distribution being bootstrapped, and use .IR KEYRING to check signatures of retrieved Release files. .IP .IP "\fB\-\-no-check-gpg\fP" Disables checking gpg signatures of retrieved Release files. .IP .IP "\fB\-\-force-check-gpg\fP" Forces checking Release file signatures, disabling automatic fallback to HTTPS in case of a missing keyring. Incompatible with the previous option. .IP .IP "\fB\-\-verbose\fP" Produce more info about downloading. .IP .IP "\fB\-\-print\-debs\fP" 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. .IP .IP "\fB\-\-download\-only\fP" Download packages, but don't perform installation. .IP .IP "\fB\-\-foreign\fP" 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 \fB\-\-second\-stage\fP option to complete the bootstrapping process. .IP .IP "\fB\-\-second\-stage\fP" Complete the bootstrapping process. Other arguments are generally not needed. .IP .IP "\fB\-\-second\-stage\-target=DIR\fP" Run second stage in a subdirectory instead of root. (can be used to create a foreign chroot) (requires \-\-second\-stage) .IP .IP "\fB\-\-keep\-debootstrap\-dir\fP" Don't delete the /debootstrap directory in the target after completing the installation. .IP .IP "\fB\-\-unpack\-tarball=FILE\fP" Acquire .debs from tarball FILE instead of downloading via http. .IP .IP "\fB\-\-make\-tarball=FILE\fP" Instead of bootstrapping, make a tarball (written to FILE) of the downloaded packages. The resulting tarball may be passed to a later .BR \-\-unpack\-tarball . .IP .IP "\fB\-\-debian\-installer\fP" Used for internal purposes by the debian-installer .IP .IP "\fB\-\-extractor=TYPE\fP" Override automatic .deb extractor selection to .IR TYPE . Supported extractors are: dpkg-deb and ar. .IP .IP "\fB\-\-no\-check\-certificate\fP" Do not check certificate against certificate authorities .IP .IP "\fB\-\-certificate=FILE\fP" Use the client certificate stored in file (PEM) .IP .IP "\fB\-\-private\-key=FILE\fP" Read the private key from file .SH EXAMPLES . .PP To setup a \fIstretch\fR system: .PP debootstrap stretch ./stretch-chroot http://deb.debian.org/debian .PP debootstrap stretch ./stretch-chroot file:///LOCAL_MIRROR/debian .PP Full process to create a complete Debian installation of \fIsid\fR (unstable) in a chroot: .PP main # debootstrap sid sid-root http://deb.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 .SH AUTHOR .B debootstrap was written by Anthony Towns .
