在windows的下的wsl安装纯自由内核，在专有软件的监牢中仰望自由
Posted 16 months ago windows cli linux bash microsoft
上回说到。我的x79主机用上了一颗有信仰的cpu
那软件也要有信仰加成
于是我决定 给wsl 换上librekernel内核（gnu认证纯自由软件内核）
https://www.fsfla.org/ikiwiki/selibre/linux-libre/
直接去下载 linux-libre.fsfla.org/pub/linux-libre/releases/
然后下载
https://github.com/microsoft/WSL2-Linux-Kernel
给ubuntu 安装编译环境
sudo apt install build-essential flex bison dwarves libssl-dev libelf-dev
复制出配置文件到新的libre kernel目录
cp Microsoft/config-wsl linux-6.2/
编辑配置 打开kvm等配置(只粘贴了部分配置，太长了。。 酌情替换)

make KCONFIG_CONFIG=config-wsl -j15
在windows下的 ~目录下 touch .wslconfig

重启wsl
wsl --shutdown
wsl uname -a
