+Adoption of a distribution-wide Code of Conduct

+- Date proposed: 2021-09-15

+
+Summary
+-------
+
+The adoption of a distribution-wide Code of Conduct (CoC) helps to describe the
+social contract by which communication takes place on the various communication
+channels offered by Arch Linux. This document describes the current CoC, its
+purpose and location and how to interact with it.
+
+Motivation
+----------
+
+A Code of Conduct is a useful document to describe the *"norms, rules, and
+responsibilities or proper practices of an individual party or an
+organization"* (see `Wikipedia article
+<https://en.wikipedia.org/wiki/Code_of_conduct>`_). Arch Linux is a community
+of entities, that consists of direct participants such as `developers
+<https://archlinux.org/people/developers/>`_, `trusted users
+<https://archlinux.org/people/trusted-users/>`_, `support
+staff <https://archlinux.org/people/support-staff/>`_ and users that
+communicate with one another over various channels. As with all social
+constructs, the Arch Linux community is not immune to disagreements on
+technical or personal level.
+
+To maintain a respectful tone and cooperation a Code of Conduct is used in
+various organizations (e.g. see `Fedora Code of Conduct
+<https://docs.fedoraproject.org/en-US/project/code-of-conduct/>`_ or `Debian
+Code of Conduct <https://www.debian.org/code_of_conduct>`_) to outline accepted
+behavior within a community.
+
+Historically, a Code of Conduct document for Arch Linux has been written,
+extended and maintained by several staff members `in the Arch Wiki
+<https://wiki.archlinux.org/index.php?oldid=648541&date-range-to=2021-01-09&action=history>`_.
+This document, although widely used througout the distribution on e.g. the
+forums, the mailing lists, the bug tracker, official IRC channels and the wiki
+has not been officially ratified.
+
+`The current version of this document
+<https://gitlab.archlinux.org/archlinux/service-agreements/-/blob/fc8b06200257ee55e060277c94d756ddfe77632c/content/docs/code-of-conduct.md>`_
+is now part of `Arch Linux's Service Agreements
+<https://gitlab.archlinux.org/archlinux/service-agreements>`_.
+
+Specification
+-------------
+
+The `Arch Linux Code of Conduct
+<https://terms.archlinux.org/docs/code-of-conduct/>`_ is part of and defined in
+the distribution's `Service Agreements <https://terms.archlinux.org/>`_.
+It describes the norms and rules by which to conduct oneself when participating
+in the various communication channels that Arch Linux offers. Additionally it
+provides information on the enforcement of the rules, as well as whom to
+contact in case of misconduct.
+
+As a central document to the distribution it is hereby officially adopted in
+`its current form
+<https://gitlab.archlinux.org/archlinux/service-agreements/-/blob/fc8b06200257ee55e060277c94d756ddfe77632c/content/docs/code-of-conduct.md>`_,
+so that it is recognized and valued by all direct participants and users.
+
+The Code of Conduct is a living document that may change over time. Changes are
+applied by merge request towards the `Service Agreements repository
+<https://gitlab.archlinux.org/archlinux/service-agreements/>`_. Any
+contributions follow the repository's contribution guidelines.
+
+The document is part of the Arch Linux Service Agreements and as such changes
+to it do not go into effect right away, but require the distribution to
+notify all service users in advance in accordance with the `Terms of Service
+Amendments section
+<https://terms.archlinux.org/docs/terms-of-service/#_amendments>`_.
+
+Drawbacks
+---------
+
+Code of Conduct documents may be abused by individuals or organizations to
+achieve the means of becoming immune to criticism (e.g. see `Straw man
+<https://en.wikipedia.org/wiki/Straw_man>`_ or `Tu quoque
+<https://en.wikipedia.org/wiki/Tu_quoque>`_ fallacies).
+
+Unresolved Questions
+--------------------
+
+Alternatives Considered
+-----------------------
+
+Over the years conflicts among members of the Arch Linux community have been
+raised, evaluated and (hopefully) solved over the various communication
+channels.
+However, a shared document, such as a Code of Conduct is without alternative
+when attempting to apply the same rules to all members of a community, as
+otherwise they would vary depending on communication channel or group within
+the community.
