                In theory, it now supports gemini-cli, claude code, opencode, and GitHub Copilot. However, the relevant agents.md needs to be set to the filename required by each agent CLI or placed in the corresponding location; otherwise, it won't take effect.
              
          
    Gentoo Overlay Development Guide

Project Overview

This guide is specifically tailored for Gentoo projects. It assumes the repository root contains a typical Gentoo overlay structure, including profiles/eapi.
This repository is a Gentoo overlay containing custom ebuilds for packages not available in the official Gentoo portage tree.
Ebuild Guidelines

Core Principles


Adhere strictly to Gentoo's ebuild standards and best practices.

                Place it in the directory .github/copilot-instructions.md, use VSCode GitHub Copilot to automate ebuild operations (upgrades, etc.). If using Claude code, you can rename this file to CLAUDE.md and place it in the root directory. Experimental! Use claude-sonnet-4 for better results.

    The Gentle Singularity  温柔的奇点
We are past the event horizon[^1]; the takeoff has started. Humanity is close to building digital superintelligence, and at least so far it’s much less weird than it seems like it should be.
我们已经越过了事件视界；起飞已经开始。人类即将建造出数字超级智能，至少到目前为止，它远比我们想象的要平淡无奇。
Robots are not yet walking the streets, nor are most of us talking to AI all day. People still die of disease, we still can’t easily go to space, and there is a lot about the universe we don’t understand.
机器人尚未走上街头，大多数人也没有整天与 AI 对话。人们仍会因病去世，我们仍无法轻松进入太空，宇宙中还有许多我们无法理解的事物。
And yet, we have recently built systems that are smarter than people in many ways, and are able to significantly amplify the output of people using them. The least-likely part of the work is behind us; the scientific insights that got us to systems like GPT-4 and o3 were hard-won, but will take us very far.

                Gentoo 使用系列之三：精简 linux-firmware
              
          
    Important
假设你定制内核（或 gentoo-kernel 通用编译）使用的是模块化而不是固件编译进内核。
本文后续将在 gentoo wiki上维护：https://wiki.gentoo.org/wiki/User:Douglarek/Streamlining_linux-firmware

书接上文[^1]，相对于定制内核来说，精简 linux-firmware[^2] 还是简单很多却是收益最大的。
在 Gentoo 中，如果不把 linux-firmware 编译进内核（有许可问题），那么运行系统除了 Linux 内核之外还是需要安装这个包的，
但是这个包包含的是 Linux 目前的所有私有固件相关的二进制[^3]，大小达 1.2G 之巨，但是一个桌面系统运行起来需要的也不过其中 3、5 个文件。
下面让我们来精简它。

                Gentoo 使用系列之二：定制内核
              
          
    Warning
当你开始定制内核的时候，你将会有大把时间用来浪（xué）费（xí）。
本文后续会在 gentoo wiki 更新：https://wiki.gentoo.org/wiki/User:Douglarek/Streamlining_kernel

本文灵感来自 reddit[^0] 上一位使用 Gentoo 的老哥，根据他提供的链接一路追到了他在 Gentoo wiki 上的文章[^1]，他这篇文章比较简洁，只是其中一些东西没说太清楚，而且也不太符合 Gentoo 本身的做法，另外文中的 gentoo-sources 似无必要，直接使用 Distribution Kernel[^9] 即可，这两个的唯一区别是如果你需要手动编译那么使用前者即可，如果是使用常规的 emerge 安装，并且享受系统安装带来的各种便利（如各种 portage 钩子），那么使用后者即可。
本文并不打算深入内核定制的细节（目前这方面我也是新手），主打一个清晰明了的流程走通，享受定制内核带来的编译时间的极大缩短（我的测试是大约能节省 2 倍左右的编译时间）。另外亦不介绍定制后内核的引导问题，毕竟这些无论是 Grub 还是 Systemd-boot 都有相关的 portage 钩子可做，假设你已经配置（否则需要手动处理）。
本文以 gentoo-kernel 为例（假设你当前安装的是 gentoo-kernel-bin 内核），分为以下几个步骤。

                Gentoo 使用系列之一：使用 systemd-boot 引导
              
          
    Important
当前（截止到 2024.11.24） systemd-boot[^1]：

只支持 UEFI（这可能是也是设计使然）
ESP 发现只能在一个分区进行，如果你的其他系统安装在不同的 ESP 分区，则无法引导
具有相比 Grub 更少的依赖，systemd 本身就支持
对于 Gentoo 来说，并不需要手动添加内核启动项，sys-kernel/installkernel[^2] 会自动创建

本文后续将在 gentoo wiki 维护：https://wiki.gentoo.org/wiki/User:Douglarek/Use_systemd-boot

本文假设你的 ESP 分区设置在 /efi，使用的 init 系统是 systemd，当前在用的是 Grub 引导，如果不是，则需要根据实际情况修改。
