## NAME
       debrebuild - use a buildinfo file and snapshot.d.o to recreate binary packages

## SYNOPSIS
       **debrebuild** [_options_] _<buildinfo>_

## DESCRIPTION
              debrebuild <--help|-h>

       Given  a buildinfo file from a Debian package, generate instructions for attempting to repro‐
       duce the binary packages built from the associated source and build information.

## OPTIONS
       **--help**, **-h**
              Show this help and exit

### --[no-]use-tor-proxy
              Whether to  fetch  resources  via  tor  (socks://127.0.0.1:9050)  Assumes  "apt-trans‐
              port-tor" is installed both in host + chroot

### --[no-]respect-build-path
              Whether to setup the build to use the Build-Path from the provided .buildinfo file.

### --buildresults
              Directory for the build artifacts (default: ./)

       **--builder**=_BUILDER_
              Which  building software should be used. Possible values are none, sbuild, mmdebstrap,
              dpkg and sbuild+unshare. The default is none. See section BUILDER for details.

       Note: debrebuild can parse buildinfo files with and without a GPG  signature.   However,  the
       signature  (if present) is discarded as debrebuild does not support verifying it.  If the au‐
       thenticity or integrity of the buildinfo files are important to you, checking these  need  to
       be done before invoking debrebuild, for example by using dscverify.

       EXAMPLES

              $ debrebuild --buildresults=./artifacts --builder=mmdebstrap hello_2.10-2_amd64.build‐
              info

       BUILDERS

       debrebuild can use different backends to perform the actual  package  rebuild.   The  desired
       backend is chosen using the **--builder** option. The default is "none".

       none   Dry-run mode. No build is performed.

       sbuild Use sbuild to build the package. This requires sbuild to be setup with schroot chroots
              of Debian stable distributions.

       mmdebstrap
              Use mmdebstrap to build the package. This requires no setup and  no  superuser  privi‐
              leges.

       dpkg   Directly  run apt-get and dpkg-buildpackage on the current system without chroot. This
              requires root privileges.

       sbuild+unshare
              Use sbuild with the unshare backend. This will create the chroot and perform the build
              without superuser privileges and without any setup.

       UNSHARE

       Before  kernel  5.10.1 or before Debian 11 (Bullseye), unprivileged user namespaces were dis‐
       abled in Debian for security reasons. Refer to Debian bug #898446 for details. To enable user
       namespaces, run:

              $ sudo sysctl -w kernel.unprivileged_userns_clone=1

       The  sbuild+unshare builder requires and the mmdebstrap builder benefits from having unprivi‐
       leged user namespaces activated. On Ubuntu they are enabled by default.

       LIMITATIONS

       Currently, the code assumes that all packages were at some  point  part  of  Debian  unstable
       main.  This  fails  for packages from Debian ports, packages from experimental as well as for
       locally built packages or packages from third party repositories. Enabling support for Debian
       ports and experimental is conceptually possible and only needs somebody implementing it.
