NAME
debootsnap - create debian chroot using snapshot.debian.org
DESCRIPTION
usage: debootsnap [-h] [--architecture ARCHITECTURE] [--ignore-notfound]
(--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 result 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.debian.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
