Import Rocky Linux to WSL¶

Prerequisites¶

The Windows-Subsystem for Linux feature has to be enabled. This is possible with one of these options:

A newer WSL version with extra features is available in the Microsoft Store. Use this newer version whenever possible.
Open an administrative Terminal (either PowerShell or Command-Prompt) and run wsl --install (ref.)
Go to the graphical Windows Settings and enable the optional feature Windows-Subsystem for Linux

This feature should be available on every supported version of Windows 10 and 11 currently.

WSL version

Ensure that your WSL version is up to date, as some features were only introduced in later versions. If you are unsure, run wsl --update.

Steps¶

Installable WSL images (preferred)¶

Download the WSL image from the CDN or another mirror closer to you:
- 9: x86_64 or aarch64
- 10: x86_64 or aarch64
There are multiple options for installing a .wsl image:
- Double-click the image and it will be installed with the images default name
- Install the image via command line:
```
wsl --install --from-file <path-to/Rocky-10-WSL-Base.latest.x86_64.wsl> <machine-name>
```

Conventional Container images¶

Get the container rootfs. This is possible in multiple ways:
- Download the image from the CDN:
  - 8: Base x86_64, Minimal x86_64, UBI x86_64, Base aarch64, Minimal aarch64, UBI aarch64
  - 9: Base x86_64, Minimal x86_64, UBI x86_64, Base aarch64, Minimal aarch64, UBI aarch64
  - 10: Base x86_64, Minimal x86_64, UBI x86_64, Base aarch64, Minimal aarch64, UBI aarch64
- Extract the image from either Docker Hub or Quay.io (ref.)
```
<podman/docker> export rockylinux:10 > rocky-10-image.tar
```
(optional) You will have to extract the .tar file from the .tar.xz file if you are using one of the latest WSL versions
Create the directory where the WSL will store its files (mostly somewhere in the user profile)

Finally, import the image into WSL (ref.):

WSL:

wsl --import <machine-name> <path-to-vm-dir> <path-to/rocky-10-image.tar.xz> --version 1

WSL 2:

wsl --import <machine-name> <path-to-vm-dir> <path-to/rocky-10-image.tar.xz> --version 2

WSL vs. WSL 2

Generally speaking, WSL 2 should be faster than WSL, although this may vary depending on the use case.

Windows Terminal

If you have Windows Terminal installed, the new WSL distro name will appear as an option on the pull-down menu, which is quite handy for launching in the future. You can then customize it with colors, fonts, and other elements.

systemd

The WSL image is systemd-enabled by default. If you want to use the container images or build your own, you will only need to add systemd=true to the boot section in the /etc/wsl.conf file. (ref.)
