Feature request to configure /etc/wsl.conf

[kai2nenobu]

This is a feature request to configure /etc/wsl.conf for WSL distribution.

I want to mount DrvFs (Windows file systems under /mnt) by wsl-shell-user but WSL distribution mounts them by root user.

To change this behavior, it requires a manual step to change mount options in /etc/wsl.conf and restart the distribution after Vampire/setup-wsl step like below. (my workflow sample and workflow result)

      - uses: Vampire/setup-wsl@v1
        with:
          distribution: Ubuntu-20.04
          set-as-default: 'true'
          wsl-shell-user: wsl
      - name: Change mount options and restart
        shell: powershell
        run: |
          wsl -u root bash -c "printf '[automount]\nenabled = true\noptions = `"metadata,uid=1000,gid=1000,umask=22,fmask=11`"\n' | tee /etc/wsl.conf"
          wslconfig /terminate Ubuntu-20.04

If Vampire/setup-wsl has a feature to directly configure /etc/wsl.conf, it makes things simple and easy.

      - uses: Vampire/setup-wsl@v1
        with:
          distribution: Ubuntu-20.04
          set-as-default: 'true'
          wsl-shell-user: wsl
          # configure /etc/wsl.conf ("wsl-conf" is just an example)
          wsl-conf: |
            [automount]
            enabled = true
            options = "metadata,uid=1000,gid=1000,umask=22,fmask=11"

Please consider to add this feature if you like.

Thanks for the suggestion.
I like the idea, I just was not aware of /etc/wsl.conf or it might have been there right away.
I even like the wording you used.
This feature will be part of 1.2 which will be released in the next hours most probably.

In case someone else is looking about securing the file permissions on WSL, config below works with Ansible.

# /etc/wsl.conf
[automount]
enabled = true
root = /
options = "metadata,umask=077"
[interop]
enabled = false
appendWindowsPath = false

Be careful if you change other options as I seen setup-wsl stop working on some of them.
