Franco Fichtner 855dbea44a system: fix automation user scope set since validation was tightened; closes #11192
While here remove the defunct -o option since it is broken and would
not make any sense anyway with the current validations in place.

Also make the script a bit prettier in use from the command line.

OPNsense GUI and system management

The OPNsense project invites developers to start contributing to the code base. For your own purposes or – even better – to join us in creating the best open source firewall available.

The build process has been designed to make it easy for anyone to build and write code. The main outline of the new codebase is available at:

https://docs.opnsense.org/development/architecture.html

Our aim is to gradually evolve to a new codebase instead of using a big bang approach into something new.

Build tools

To create working software like OPNsense you need the sources and the tools to build it. The build tools for OPNsense are freely available.

Notes on how to build OPNsense can be found in the tools repository:

https://github.com/opnsense/tools

Contribute

You can contribute to the project in many ways, e.g. testing functionality, sending in bug reports or creating pull requests directly via GitHub. Any help is always very welcome!

You can learn more about contributing on CONTRIBUTING.md.

License

OPNsense is and will always be available under the 2-Clause BSD license:

https://opensource.org/licenses/BSD-2-Clause

Every contribution made to the project must be licensed under the same conditions in order to keep OPNsense truly free and accessible for everybody.

Makefile targets

The repository offers a couple of targets that either tie into tools.git build processes or are aimed at fast development.

make package

A package of the current state of the repository can be created using this target. It may require several packages to be installed. The target will try to assist in case of failure, e.g. when a missing file needs to be fetched from an external location.

Several OPTIONS exist to customise the package, e.g.:

  • CORE_DEPENDS: a list of required dependencies for the package
  • CORE_DEPENDS_ARCH: a list of special -required packages
  • CORE_ORIGIN: sets a FreeBSD compatible package/ports origin
  • CORE_COMMENT: a short description of the package
  • CORE_MAINTAINER: email of the package maintainer
  • CORE_WWW: web url of the package
  • CORE_NAME: sets a package name

Options are passed in the following form:

# make package CORE_NAME=my_new_name

In general, options are either set to sane defaults or automatically detected at runtime.

make update

Update will pull the latest commits from the current branch from the upstream repository.

make upgrade

Upgrade will run the package build and replace the currently installed package in the system.

make collect

Fetch changes from the running system for all known files.

make lint

Run several syntax checks on the repository. This is recommended before issuing a pull request on GitHub.

make style

Run the PSR12 and PEP8 style checks on MVC PHP code and Python, respectively.

For easier development you may want to use an OPNsense VM and install the os-debug plugin that will offer the necessary tools.

make sweep

Run several automatic sanitizers on the code base.
