DEBOOTSNAP(1) User Commands DEBOOTSNAP(1) NAME debootsnap - create debian chroot using snapshot.debian.org DESCRIPTION usage: debootsnap [-h] [--architecture ARCHITECTURE] [--ignore-not- found] (--buildinfo BUILDINFO | --packages PACKAGES) [--sources-list-only] [output] Combines debootstrap and snapshot.debian.org to create a chroot with exact package versions from the past either to reproduce bugs or to test source package reproducibility. To obtain a list of packages run the following command on one machine: $ dpkg-query --showformat '${binary:Package}=${Version}\n' --show And pass the output to debootsnap with the --packages argument. The re- sult will be a chroot tarball with precisely the package versions as they were found on the system that ran dpkg-query. positional arguments: output path to output chroot tarball options: -h, --help show this help message and exit --architecture ARCHITECTURE, --nativearch ARCHITECTURE native architecture of the chroot. Ignored if --buildinfo is used. Foreign architectures are inferred from the package list. Not required if packages are architecture qualified. --ignore-notfound only warn about packages that cannot be found on snapshot.de- bian.org instead of exiting --buildinfo BUILDINFO use packages from a buildinfo file. Read buildinfo file from standard input if value is "-". --packages PACKAGES, --pkgs PACKAGES list of packages, optional architecture and version, separated by comma or linebreak. Read list from standard input if value is "-". Read list from a file if value starts with "./" or "/". The option can be specified multiple times. Package name, version and architecture are separated by one or more characters that are not legal in the respective adjacent field. Leading and trailing illegal characters are allowed. Example: pkg1:arch=ver1,pkg2:arch=ver2 --sources-list-only only query metasnap.debian.net and print the sources.list needed to create chroot and exit EXAMPLES On one system run: $ dpkg-query --showformat '${binary:Package}=${Version}\n' --show > pkglist Then copy over "pkglist" and on another system run: $ debootsnap --pkgs=./pkglist chroot.tar Or use a buildinfo file as input: $ debootsnap --buildinfo=./package.buildinfo chroot.tar debootsnap 2.23.4+deb12u1 October 2023 DEBOOTSNAP(1)
