sbuild.conf - configuration file for sbuild

sbuild.conf is a Perl script which is sourced by sbuild to permit configuration. It is run in a sandbox and restricted to setting a small number of variables, detailed below, which may be set to configure the behaviour of sbuild. Each variable has an internal name, shown in all caps, and a perl variable showing the default setting. Note that the internal name is not accessible within sbuild.conf; only the variable may be assigned. Also note that some of the defaults are set to be unique for each build, and so some of the defaults shown here are unique to the user and system used to build sbuild, and will be different for your system.

While sbuild permits many aspects of its behaviour to be configured, this should not normally be required. The defaults should be adequate for most uses, and should only be changed if you are doing something more advanced, or have specialist requirements.

STRING type. Library search path to use inside the chroot.
Related sbuild(1) command line options:

--use-snapshot
Default:

$ld_library_path = undef;
STRING type. PATH to set when running dpkg-buildpackage.
Related sbuild(1) command line options:

--use-snapshot
Default:

$path = '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games';

STRING type. Suffix to append to version number. May be useful for derivative distributions.
Related sbuild(1) command line options:

--append-to-version
Default:

$append_to_version = undef;
STRING type. Binary NMU changelog entry.
Related sbuild(1) command line options:

--make-binNMU
Default:

$bin_nmu = undef;
STRING type. The content of a binary-only changelog entry. Leading and trailing newlines will be stripped.
Related sbuild(1) command line options:

--binNMU-changelog
Default:

$bin_nmu_changelog = undef;
STRING type. Binary NMU timestamp. The timestamp is either given as n integer in Unix time or as a string in the format compatible with Debian changelog entries (i.e. as it is generated by date -R). If set to the default (undef) the date at build time is used.
Related sbuild(1) command line options:

--binNMU-timestamp
Default:

$bin_nmu_timestamp = undef;
STRING type. Binary NMU version number.
Related sbuild(1) command line options:

--binNMU
--make-binNMU
Default:

$bin_nmu_version = undef;
STRING type. Build architecture (Arch we are building on).
Related sbuild(1) command line options:

--arch
--build

build_arch = ...;
BOOL type. Build architecture: all packages by default.
Related sbuild(1) command line options:

--arch-all
--no-arch-all
Default:

$build_arch_all = undef;
BOOL type. Build architecture: any packages by default.
Related sbuild(1) command line options:

--arch-any
--no-arch-any
Default:

$build_arch_any = 1;
STRING type. This command is run with the dpkg-buildpackage command line passed to it (in the chroot, if doing a chrooted build). It is used by the sparc buildd (which is sparc64) to call the wrapper script that sets the environment to sparc (32-bit). It could be used for other build environment setup scripts. Note that this is superseded by schroot's 'command-prefix' option
Default:

$build_env_cmnd = '';
STRING type. By default the package is built in a path of the following format /build/packagename-XXXXXX/packagename-version/ where XXXXXX is a random ascii string. This option allows one to specify a custom path where the package is built inside the chroot. The sbuild user in the chroot must have permissions to create the path. Common writable locations are subdirectories of /tmp or /build. Using /tmp might be dangerous, because (depending on the chroot backend) the /tmp inside the chroot might be a world writable location that can be accessed by processes outside the chroot. The directory /build can only be accessed by the sbuild user and group and should be a safe location. The buildpath must be an empty directory because the last component of the path will be removed after the build is finished. Notice that depending on the chroot backend (see CHROOT_MODE), some locations inside the chroot might be bind mounts that are shared with other sbuild instances. You must avoid using these shared locations as the build path or otherwise concurrent runs of sbuild will likely fail. With the default schroot chroot backend, the directory /build is shared between multiple schroot sessions. You can change this behaviour in /etc/schroot/sbuild/fstab. The behaviour of other chroot backends will vary.
Related sbuild(1) command line options:

--build-path
Default:

$build_path = undef;
STRING type. Build profiles. Separated by spaces. Defaults to the value of the DEB_BUILD_PROFILES environment variable when building natively and to the cross and nocheck profiles when cross-building.
Related sbuild(1) command line options:

--profiles
Default:

$build_profiles = undef;
BOOL type. By default, do not build a source package (binary only build). Set to 1 to force creation of a source package, but note that this is inappropriate for binary NMUs, where the option will always be disabled.
Related sbuild(1) command line options:

-s
--source
--no-source
Default:

$build_source = 0;
BOOL type. Check free disk space prior to starting a build. sbuild requires the free space to be at least twice the size of the unpacked sources to allow a build to proceed. Can be disabled to allow building if space is very limited, but the threshold to abort a build has been exceeded despite there being sufficient space for the build to complete.
Default:

$check_space = 1;
BOOL type. When running sbuild from within an unpacked source tree, run the 'clean' target before generating the source package. This might require some of the build dependencies necessary for running the 'clean' target to be installed on the host machine. Only disable if you start from a clean checkout and you know what you are doing.
Related sbuild(1) command line options:

--clean-source
--no-clean-source
Default:

$clean_source = 1;
STRING type. Default distribution. By default, no distribution is defined, and the user must specify it with the -d option. However, a default may be configured here if desired. Users must take care not to upload to the wrong distribution when this option is set, for example experimental packages will be built for upload to unstable when this is not what is required.
Related sbuild(1) command line options:

-d
--dist
Default:

$distribution = undef;
BOOL type. By default, the -s option only includes the .orig.tar.gz when needed (i.e. when the Debian revision is 0 or 1). By setting this option to 1, the .orig.tar.gz will always be included when -s is used.
Related sbuild(1) command line options:

--force-orig-source
Default:

$force_orig_source = 0;
BOOL type. Build using current GCC snapshot?
Related sbuild(1) command line options:

'linux-libc-dev$',
'gnumach-dev$',
'hurd-dev$',
'kfreebsd-kernel-headers$'
];

HASH:NUMERIC type. Some packages may exceed the general timeout (e.g. redirecting output to a file) and need a different timeout. This has is a mapping between source package name and timeout. Note that for backward compatibility, this is also settable using the hash %individual_stalled_pkg_timeout (deprecated) , rather than a hash reference.
Example:

$individual_stalled_pkg_timeout->{'llvm-toolchain-3.8'} = 300;
$individual_stalled_pkg_timeout->{'kicad-packages3d'} = 90;
Default:

--run-piuparts
--no-run-piuparts
Default:

$run_piuparts = 0;

BOOL type. Force APT to accept unauthenticated packages. By default, unauthenticated packages are not allowed. This is to keep the build environment secure, using apt-secure(8). By setting this to 1, APT::Get::AllowUnauthenticated is set to "true" when running apt-get. This is disabled by default: only enable it if you know what you are doing.
Default:

Default:

$apt_keep_downloaded_packages = 0;
BOOL type. APT update. 1 to enable running "apt-get update" at the start of each build, or 0 to disable. This option has no effect on updating the internal sbuild apt repository, the repository for extra packages (see EXTRA_PACKAGES) and the repositories given via EXTRA_REPOSITORIES.

STRING type. When to purge the build directory after a build; possible values are "never", "successful", and "always"
Related sbuild(1) command line options:

-p
--purge
--purge-build
Default:

$purge_build_directory = 'always';
BOOL type. Try to remove all additional packages that are not strictly required for the build right after build dependencies were installed. This currently works best with the aspcud resolver. The apt resolver will not make as much effort to remove all unneeded packages and will keep all providers of a virtual package and all packages from any dependency alternative that happen to be installed. The aptitude and xapt resolver do not implement this feature yet. The removed packages are not yet added again after the build finished. This can have undesirable side effects like lintian not working (because there is no apt to install its dependencies) or bare chroots becoming totally unusable after apt was removed from them. Thus, this option should only be used with throw-away chroots like schroot provides them where the original state is automatically restored after each build.
Related sbuild(1) command line options:

--purge-extra-packages
Default:

$purge_extra_packages = 0;
STRING type. Purge the schroot session following a build. This is useful in conjunction with the --purge and --purge-deps options when using snapshot chroots, since by default the snapshot will be deleted. Possible values are "always" (default), "never", and "successful"

STRING type. Output directory for build artifacts created by dpkg-buildpackage and the log file. Defaults to the current directory if unspecified. It is used as the location of chroot symlinks (obsolete) and for current build log symlinks and some build logs. There is no default; if unset, it defaults to the current working directory. $HOME/build is another common configuration.

Example:

$build_dir = '/home/pete/build';

build_dir = ...;
HASH:STRING type. Environment to set during the build. Defaults to setting PATH and LD_LIBRARY_PATH only. Note that these environment variables are not subject to filtering with ENVIRONMENT_FILTER. Example:
Example:

$build_environment = {
'CCACHE_DIR' => '/build/cache'
};
Default:

$build_environment = {};
STRING type. Username used for running dpkg-buildpackage. By default the user running sbuild is used within the chroot as well but that might allow a process from within the chroot to break out of the chroot by attaching to a process running outside the chroot with eg. gdb and then becoming root inside the chroot through schroot and thus be able to leave the chroot.

build_user = ...;
ARRAY:STRING type. Packages which must be installed in the chroot for all builds.
Default:

$core_depends = [
'build-essential:native',
'fakeroot:native'
];
ARRAY:STRING type. Only environment variables matching one of the regular expressions in this arrayref will be passed to dpkg-buildpackage and other programs run by sbuild. The default value for this configuration setting is the list of variable names as returned by Dpkg::Build::Info::get_build_env_allowed() which is also the list of variable names that is whitelisted to be recorded in .buildinfo files. Caution: the default value listed below was retrieved from the dpkg Perl library version available when this man page was generated. It might be different if your dpkg Perl library version differs.

STRING type. sbuild behaviour; possible values are "user" (exit status reports build failures) and "buildd" (exit status does not report build failures) for use in a buildd setup. "buildd" also currently implies enabling of "legacy features" such as chroot symlinks in the build directory and the creation of current symlinks in the build directory.
Related sbuild(1) command line options:

--sbuild-mode
Default:

$sbuild_mode = 'user';

STRING type. Optimization criteria in extended MISC 2012 syntax passed to aspcud through apt-cudf. Optimization criteria are separated by commas, sorted by decreasing order of priority and are prefixed with a polarity (+ to maximize and - to minimize). The default criteria is '-removed,-changed,-new' which first minimizes the number of removed packages, then the number of changed packages (up or downgrades) and then the number of new packages. A common task is to minimize the number of packages from experimental. To do this you can add a criteria like '-count(solution,APT-Release:=/a=experimental/)' to the default criteria. This will then minimize the number of packages in the solution which contain the string 'a=experimental' in the 'APT-Release' field of the EDSP output created by apt. See the apt-cudf man page help on the --criteria option for more information.

--bd-uninstallable-explainer
Default:

$bd_uninstallable_explainer = 'dose3';
STRING type. Build dependency resolver. The 'apt' resolver is currently the default, and recommended for most users. This resolver uses apt-get to resolve dependencies. Alternative resolvers are 'apt', 'aptitude' and 'aspcud'. The 'apt' resolver uses a built-in resolver module while the 'aptitude' resolver uses aptitude to resolve build dependencies. The aptitude resolver is similar to apt, but is useful in more complex situations, such as where multiple distributions are required, for example when building from experimental, where packages are needed from both unstable and experimental, but defaulting to unstable. If the dependency situation is too complex for either apt or aptitude to solve it, you can use the 'aspcud' resolver which (in contrast to apt and aptitude) is a real solver (in the math sense) and will thus always find a solution if a solution exists. Additionally, the 'null' solver is provided. It is a dummy resolver which does not install, upgrade or remove any packages. This allows one to completely control package installation via hooks.

Default:

$extra_repository_keys = [];
BOOL type. Should the dependency resolver use alternatives in Build-Depends, Build-Depends-Arch and Build-Depends-Indep? By default, using 'apt' resolver, only the first alternative will be used; all other alternatives will be removed. When using the 'aptitude' resolver, it will default to using all alternatives. Note that this does not include architecture-specific alternatives, which are reduced to the build architecture prior to alternatives removal. This should be left disabled when building for unstable; it may be useful when building for experimental or backports. Set to undef to use the default, 1 to enable, or 0 to disable.
