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
