       debspawn - Build in nspawn containers


       debspawn [-h|--help] [-c|--config] [--verbose] [--no-unicode] [--version] [--owner]


       This manual page documents the debspawn command.

       debspawn is a tool to build Debian packages in an isolated environment, using nspawn
       containers. By using containers, debspawn can isolate builds from the host system much
       further. It also allows for more advanced features to manage builds, for example setting
       resource limits for individual builds.

       Please keep in mind that debspawn is not a security feature! While it provides a lot of
       isolation from the host system, you should not run arbitrary untrusted code with it. The
       usual warnings for all container technology apply here. See systemd-nspawn(1) for more
       information on the container solution debspawn uses.

       Debspawn also allows one to run arbitrary custom commands in its environment. This is
       useful to execute a variety of non-package build and QA actions in the same environment in
       which packages are normally built.

       For more information about the DebSpawn project, you can visit its project page[1].


       debspawn actions are invoked via subcommands. Refer to their individual manual pages for
       further details.

           Create a new container base image for a specific suite, architecture and variant. A
           custom mirror location can also be provided. For details, see debspawn-create(1).

           Delete a container base image and all data associated with it. For details, see

           Update a container base image, ensuring all packages are up to date and all required
           scripts are installed. For details, see debspawn-update(1).

           Build a Debian package in an isolated environment. For details, see debspawn-build(1).

           Get an interactive shell session in a container. For details, see debspawn-login(1).

           Run arbitrary commands in debspawn container session. This is primarily useful for
           using debspawn from another script. For details, see debspawn-run(1).


           Print brief help information about available commands.

           Path to the global config file.

           Enable debug messages.

           Disable unicode support.

           Display the version of debspawn itself.

           Set the user name/uid and group/gid separated by a colon whose behalf we are acting.
