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'.
--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.

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:

% sudo sbuild-createchroot sid /srv/chroot/unstable-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).
