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
