NAME

sbuild-createchroot - create sbuild chroot

SYNOPSIS

sbuild-createchroot [-h|--help | -V|--version] [--verbose] [--arch=arch] [--chroot-suffix=suffix] [--foreign] [--resolve-deps | --no-resolve-deps] [--keep-debootstrap-dir] [--debootstrap=debootstrap] [--include= package1[,package2,[packagen]]] [--exclude=package1[,package2,[packagen]]] [--components=component1[,component2,[componentn]]] [--keyring= keyring-file] [--setup-only] [--make-sbuild-tarball= file] [--keep-sbuild-chroot-dir] [--no-deb-src] [--alias=alias] [--extra-repository=spec] SUITE TARGET-DIRECTORY DEBIAN-MIRROR-URI [SCRIPT]
buildd-create-chroot USER SUITE TARGET-DIRECTORY DEBIAN-MIRROR-URI

DESCRIPTION

sbuild-createchroot runs debootstrap(1) to create a chroot suitable for building packages with sbuild. Note that while debootstrap may be used directly, sbuild-createchroot performs additional setup tasks such as adding additional packages and configuring various files in the chroot. Invoking sbuild-createchroot is functionally equivalent to running debootstrap --variant=buildd --include=fakeroot,build-essential, then editing /etc/apt/sources.list and /etc/hosts by hand.
The newly-created chroot is set up to work with schroot(1) by creating a chroot definition file under /etc/schroot/chroot.d. This should be edited to finish the chroot configuration after sbuild-createchroot has completed.
buildd-create-chroot, like sbuild-createchroot, runs debootstrap(1) to create a chroot for package building. However, this creates a chroot specifically for buildd(1) with an additional mandatory option to specify a user who will be granted sudo access inside the chroot. This script mainly differs in its additional customisation of /etc/apt/sources.list to use incoming.debian.org and security-master.debian.org. It also removes some packages from the newly-created chroot. Unless you are setting up an official Debian build daemon, sbuild-createchroot should be used instead. The extra functionality will be merged into sbuild-createchroot in the future.

OPTIONS

Actions

-h, --help
Display this manual.
-V, --version
Print version information.

General options

-v, --verbose
Print all messages.

Debootstrap options

Note that debootstrap(1) is the canonical reference for the meaning of the options; they are passed directly to debootstrap.
--arch=arch
Set the target architecture. This may be used if dpkg is not already installed. See also --foreign, below.
--chroot-suffix=suffix
Add a custom suffix to the chroot name. Defaults to '-sbuild'.
--chroot-prefix=prefix
Add a custom prefix to the chroot name. Defaults to SUITE. This is useful to create variants of a base suite like jessie-backports to which the backports archive can be manually added after the base chroot was created using sbuild-shell. This way, a normal jessie chroot and a jessie-backports chroot can exist side-by-side. Besides this common use case, this functionality can also be used to create chroots with any other type of customization. It is a shortcut for creating a base chroot and then having to manually copy it and edit the configuration files.
--foreign
Only perform the initial unpack phase of bootstrapping. This is required if the target and host architectures do not match. Note that debootstrap requires running by hand to complete installation; run the debootstrap /debootstrap/debootstrap installed in TARGET-DIRECTORY to complete the installation.
--resolve-deps
Automatically resolve missing dependencies. This is the default.
--no-resolve-deps
Do not automatically resolve missing dependencies.
--keep-debootstrap-dir
Don't delete the /debootstrap directory in TARGET-DIRECTORY after completing the installation.
--debootstrap=debootstrap
Define a custom debootstrap variant. Defaults to 'debootstrap'.
--include=package1[,package2,[packagen]]
Comma separated list of packages which will be added to the list of packages to download and extract.
--exclude=package1[,package2,[packagen]]
Comma separated list of packages which will be removed from the list of packages to download and extract. Note that this can remove essential packages, so use with extreme care.
--components=component1[,component2,[componentn]]
Comma separated list of archive components to use (e.g. ‘main’, ‘contrib’, ‘non-free’). Defaults to ‘main’.
--keyring=keyring-file
Download signatures for retrieved Release files and check them against keyring-file. By default /etc/apt/trusted.gpg is used. Set to an empty string to disable signature checking.
SUITE
The distribution to bootstrap (e.g. ‘sarge’, ‘etch’, ‘lenny’, ‘sid’). A complete list may be found in /usr/share/debootstrap/scripts.
TARGET-DIRECTORY
The directory to create the chroot in. The directory will be created if it does not already exist.
DEBIAN-MIRROR-URI
An http://, file:///, or ssh:/// URI pointing to a suitable archive mirror.
SCRIPT
debootstrap script to run. Not typically required.

sbuild-createchroot behaviour

--setup-only
Don't run debootstrap. Only perform the setup tasks on an already existing chroot. This is useful for converting an existing chroot for use with sbuild which has already been created using a tool such as debootstrap.
--make-sbuild-tarball=file
Create a bootstrapped file type chroot ready for use with sbuild and save it as file. The compression format used for the tarball is dependent on the file extension used in file. See the TARBALL FILE section for more details.
--keep-sbuild-chroot-dir
Don't delete the directory used for creating a file type chroot. This option does nothing if not creating a file type chroot.
--no-deb-src
Don't add a deb-src line to the /etc/apt/sources.list file in the TARGET-DIRECTORY after the debootstrap process. This is useful in situation when it is known that sbuild will never have to download the source package itself but is always given an already downloaded dsc. In that case, this option will help to save bandwidth and disk space because the source indices don't have to be downloaded and later continually updated.
--alias=alias
Add an alternative name that the chroot will be known by. This option can be given multiple times to add more than one alias. Using an alias is useful for chroots of distributions that are known by more than one name. For example Debian unstable is also known as sid. Additionally, sbuild chooses the distribution by the latest changelog entry which could list UNRELEASED for packages that the maintainer is currently working on. For Debian it thus makes sense to add UNRELEASED as an alias for a Debian unstable chroot. See the EXAMPLES section for how to use this option in practice.
--extra-repository=spec
Add a repository to the list of apt sources. The repository specification is a line suitable for an apt sources.list(5) file. For instance, you might use --extra-repository="deb http://httpredir.debian.org/debian experimental main" to allow packages in the experimental distribution to fulfill build-dependencies. Note that the build chroot must already trust the key of this repository. See the EXAMPLES section for how to combine this option with --chroot-prefix and --alias.

TARBALL FILE

When creating an sbuild tarball file, the compression format used to generate the tarball depends on the entension used in file. Here is a listing of the extensions that will be detected and what format the tarball will be generated as.
*.tar
Generates an uncompressed tarball.
*.tar.gz|*.tgz
Generates a compressed tarball using gzip.
*.tar.bz2|*.tbz
Generates a compressed tarball using bzip2.
*.tar.lz|*.tlz
Generates a compressed tarball using lzip.
*.tar.xz|*.txz
Generates a compressed tarball using xz.
If no extension is specified, sbuild-createchroot will rename file to file.tar.gz and generate file.tar.gz as a compressed tarball using gzip.

EXAMPLES

To create a bootstrapped file type sid (unstable) chroot ready for use with sbuild and saved in /var/cache/sbuild/sbuild.tar.gz using the httpredir.debian.org Debian http mirror redirector service and using a temporary directory as the target:
% sudo sbuild-createchroot \
 

--make-sbuild-tarball=/srv/chroot/unstable-amd64.tar.gz \
 

sid `mktemp -d` \
 
http://httpredir.debian.org/debian
To create a plain type sid (unstable) chroot in /srv/chroot/unstable using the httpredir.debian.org Debian http mirror redirector service and with aliases for unstable and UNRELEASED:
% sudo sbuild-createchroot sid /srv/chroot/unstable-amd64 \
 

--alias=unstable --alias=UNRELEASED \
 
http://httpredir.debian.org/debian
To create a chroot to build for Jessie backports:
% sudo sbuild-createchroot \
 

--extra-repository="deb http://httpredir.debian.org/debian jessie-backports main" \
 

--chroot-prefix=jessie-backports \
 

jessie /srv/chroot/jessie-backports-amd64 \
 
http://httpredir.debian.org/debian
To create a chroot to build for experimental using a custom chroot prefix:
% sudo sbuild-createchroot \
 

--extra-repository="deb http://httpredir.debian.org/debian experimental main" \
 

--chroot-prefix=experimental \
 

unstable /srv/chroot/unstable-experimental-amd64 \
 
http://httpredir.debian.org/debian

HISTORY

sbuild-createchroot was previously known as buildd.chroot. buildd.chroot performed exactly the same tasks, but additionally created a number of directories in the chroot for use by sbuild. This is now done by schroot(1).
