Publish into the running instance the WSL version about wsldl HOT 5 CLOSED

You can get WSL version (1 or 2) of instance:
Launcher.exe get --wsl-version

from wsldl.

I meant to retrieve the version from the running Linux.

As I pointed in the question (made by myself) there is a not clear environment variable and the Kernel uname options, but none are official nor reliable.

So I don't know if Launcher can add environment variables before starting the WSL command line, adding that --wsl-version in a new environment variable named WSL_VERSION or similar.

If my C knowledge would not be so rusty I could set a PR, sorry :(

ah, sorry, I understood.
You are right.
Guessing the WSL version from uname is not accurate.

Now, we don't provide wsl version information to environment variable.

from wsldl.

I think it is difficult to provide that function.
Users don't always launch using our launcher.

from wsldl.

Users don't always launch using our launcher.

Yes, ideally should be that Microsoft provides it (I probably will open an issue later).
Or you mean that not everyone that has the Launcher use it as "executable" and they use the wsl command?

UPDATE: SuperUser question has a good workaround, so feel free to close this.
