To install WSL2:
https://docs.microsoft.com/en-us/windows/wsl/install-win10

To import a distro:
* Make a directory "wsl2" in your Windows home directory
* Download a Linux WSL root filesystem tar.gz file
* Copy it to your WSL2 directory
* Make a directory under WSL2 for your distro (ex. c:\Users\<user>\wsl2\Ubuntu-22.04)
* Import the tar.gz file into WSL2 using "wsl --import"

example:
> New-Item -ItemType directory C:\Users\<username>\wsl2\alpine-<date>\ (or specify alternate path)
> cd C:\Users\<username>\wsl2\alpine-<date>\
> iwr https://dl-cdn.alpinelinux.org/alpine/v3.15/releases/x86_64/alpine-minirootfs-<version>-x86_64.tar.gz -OutFile alpine-minirootfs-<version>-x86_64.tar.gz
> wsl --import Alpine-<date> C:\Users\<user>\wsl2\alpine-<date>\ C:\Users\<user>\wsl2\alpine-3.15\alpine-minirootfs-<version>-x86_64.tar.gz
> wsl -d Alpine-<date>

After importing, configure the new distro.

Alpine:
> apk add sudo bash vim openssh-client
> addgroup -g 1000 <user>
> adduser -S -u 1000 -G <user> -s /bin/bash <user>
> adduser <user> wheel
> update /etc/sudoers

Ubuntu:
> groupadd -g 1000 <user>
> useradd -r -m -u 1000 -g 1000 -s /bin/bash <user>

> visudo (add your user to sudoers file)
> exit
> wsl -d <distro> -u <user>

Notes:
Specifying a date with the distro allows for more flexability when having multiple distros or performing distro re-installs.

migrating files from one wsl2 distro to another:
* sending side: tar cvpf - /full/path | nc -w 3 localhost 1234
* recving side: nc -l -p 1234 | tar xhpf - -C /


Export distro:
> wsl -l -v
> wsl -t <distro_name>
> wsl --export <distro_name> <destination>

Import distro:
> wsl --import wsl --import <distro_name> <destination> <tar_file>

Remove distro:
> wsl --unregister <distro_name>
