[CentOS] how to run CentOS 8.2 under new WSL2?

Okay, so there are a few things here. We (the CentOS Project) don't
currently publish anything that's easily consumable into WSL2 on the
mirrors or download pages. That's probably something we should address,
or at least talk about fixing. I can provide some directions below, but
they're very rough as I only started experimenting with this last night
once I saw your email.

First, create a directory on your windows system where you're going to
store your custom distro. I used C:\distros but you can use whatever
makes sense to you.

Second, you're going to need something that can understand the xz
archive format that's used these days rather than the older gz style.
7zip should do this fine, or optionally the tools straight from the
project/author - https://tukaani.org/xz/

Next, you'll want to pull the tarball we use to publish images to the
dockerhub. We use versions branches in this repo, so you pick what you
want. Here's the one for CentOS 8 currently ->
 (Advanced users can make their own tarballs here with livemedia-creator
or whatever is preferred)

Uncompress this archive, but don't unpack it. You want to end up with

>From there, fire up a command prompt (Windows Terminal, cmd, powershell,
whatever). You can import this into wsl2 by running:
wsl.exe --import CentOS C:\distros\CentOS \path\to\CentOS-8-x86_64.tar

At this point you're "done" but it's not quite there.

if you want to stop here, you can simply run: wsl.exe -d CentOS

It'll work but you'll be running as root.

If you want to add your user, set up sudo, things like that you need to
do a bit more.

wsl.exe -d CentOS # to run it as root
useradd yourusername
dnf -y update
dnf -y install sudo # and whatever else you want
id -u yourusername # this is probably 1000
visudo # give your new user sudo access otherwise you'll lock yourself out.

Now, at this point I don't know an easy way to find the GUID of the
custom distro. I cheated and used the value from Windows Terminal's json
config file. Take that GUID and your user's UID and fire up regedit to
set your user as the default.

You'll want to look at
and set DefaultUid as a REG_DWORD to your user's uid (typically 1000).

That's as far as I've taken things so anything you want to do after this
you're kinda on your own.
