应该测试一下 wsl 的东西
wsl 居然开源了?
https://www.reddit.com/r/linux/comments/1kqgwr9/the_windows_subsystem_for_linux_is_now_open_source/ https://news.ycombinator.com/item?id=44031385
https://github.com/microsoft/WSL https://github.com/microsoft/wslg
原来一个 wsl 命令就可以了，太酷了
如何开启 wsl
- 首先，更新系统:
- 然后参考这个:
- https://ubuntu.com/tutorials/install-ubuntu-on-wsl2-on-windows-11-with-gui-support#2-install-wsl
- wsl -l -v : 检查 wsl 的版本
参考内容:
- https://www.huanlintalk.com/2020/02/wsl-2-installation.html

这的确封装的好啊
PS C:\Users\97936\data\vn> wsl --install FedoraLinux-42
正在下载: Fedora Linux 42
正在安装: Fedora Linux 42
已成功安装分发。可以通过 “wsl.exe -d FedoraLinux-42” 启动它
正在启动 FedoraLinux-42...
wsl: 检测到 localhost 代理配置，但未镜像到 WSL。NAT 模式下的 WSL 不支持 localhost 代理。
Please create a default user account. The username does not need to match your Windows username.
For more information visit: https://aka.ms/wslusers
Enter new UNIX username:
wsl –list –online
wsl -d FedoraLinux-42
wsl –set-default FedoraLinux-42 wsl –manage FedoraLinux-42 –set-default-user martins3 wsl # 然后这个就可以了 wsl –user martins3 -d FedoraLinux-42

找不到用户。
错误代码: Wsl/WSL_E_USER_NOT_FOUND
哦， mount 看到的用的也是 9p ，但是主要是各种驱动:
none on /usr/lib/modules/6.6.87.2-microsoft-standard-WSL2 type overlay (rw,nosuid,nodev,noatime,lowerdir=/modules,upperdir=/lib/modules/6.6.87.2-microsoft-standard-WSL2/rw/upper,workdir=/lib/modules/6.6.87.2-microsoft-standard-WSL2/rw/work,uuid=on)
none on /mnt/wsl type tmpfs (rw,relatime)
drivers on /usr/lib/wsl/drivers type 9p (ro,nosuid,nodev,noatime,aname=drivers;fmask=222;dmask=222,cache=5,access=client,msize=65536,trans=fd,rfd=8,wfd=8)
磁盘还是普通的磁盘:
/dev/sdd on /mnt/wslg/distro type ext4 (ro,relatime,discard,errors=remount-ro,data=ordered)
[user@martins3 distro]$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 388.4M 1 disk
sdb 8:16 0 186M 1 disk
sdc 8:32 0 4G 0 disk [SWAP]
sdd 8:48 0 1T 0 disk /mnt/wslg/distro
/
sde 8:64 0 1T 0 disk
和 hyper-v 一样的网络配置:
[user@martins3 ~]$ ip a

当执行 wsl 的时候，使用的是什么网络呢?
估计还是 nat 了
诡异的代理穿透问题
居然是 podman 虚拟机的问题，换成 fedora 虚拟机就没有问题了
不知道

可以写一个 wsl 和 ubuntu 的 multipass 的对比 blog
什么东西是 relay
才意识到，这是一个完全不同的东西: 难怪是不需要密码的:

原来 wsl 有自己的半虚拟化支持
改动不多，但是:

https://wsl.dev/
wsl 测试，在虚拟机中 git clone linux kernel ，必然导致物理机宕机
关闭 嵌套虚拟化应该可以解决这个问题
偶遇到这个错误了

难道有一个 WSL 进程么?
wsl usb manager

wsl manager : 其实功能很简单 winget install Bostrot.WSLManager
