Arch Linux hasn't had a license for any package sources (such as PKGBUILD files) in the past, which is potentially problematic. Providing a license will preempt that uncertainty. In [RFC 40](https://rfc.archlinux.page/0040-license-package-sources/) we agreed to change all package sources to be licensed under the very liberal [0BSD](https://spdx.org/licenses/0BSD.html) license. **This change will not limit what you can do with package sources**. Check out [the RFC](https://rfc.archlinux.page/0040-license-package-sources/) for more on the rationale and prior discussion. Before we make this change, we will provide contributors with a way to voice any objections they might have. Starting on 2024-11-19, over the course of a week, contributors will receive a single notification email listing all their contributions. - If you receive an email and agree to this change, there is no action required from your side. - If you do not agree, please reply to the email and we'll find a solution together. If you contributed to Arch Linux packages before but didn't receive an email, please contact us at package-sources-licensing@archlinux.org.
