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
