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.

--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.

--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 plain type sid (unstable) chroot in /srv/chroot/unstable using the  ftp.uk.debian.org  Debian
       mirror:

       % sudo sbuild-createchroot sid /srv/chroot/unstable \
           http://ftp.uk.debian.org/debian↵

       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 ftp.uk.debian.org Debian mirror and using a temporary directory
       as the target:

       % sudo sbuild-createchroot \
           --make-sbuild-tarball=/var/cache/sbuild/sbuild.tar.gz \
           sid `mktemp -d` \
           http://ftp.uk.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).
