RFC: Mirror Definition

A new RFC (request for comment) has been opened here: https://gitlab.archlinux.org/archlinux/rfcs/-/merge_requests/29 Please visit the above link for discussion. Summary: Before this proposal, there were a lack of requirements and definition of what a mirror is within the Arch Linux community. This RFC therefore outlines the requirements, definitions and guidelines surrounding both becoming but also maintaining and decommissioning a mirror.
