NixOS not detected as Linux distro

[eku]

I'm running NixOS Linux distro in WSL2.

Needless to say, Microsoft's combination of VSCode and Remote WSL works with it.

VSCodium and Open Remote WSL, on the other hand, abort with an error.

This is the place where the platform is checked:

open-remote-wsl/src/serverSetup.ts

Lines 179 to 189 in 20824d5

	# Check if platform is supported
	PLATFORM="$(uname -s)"
	case $PLATFORM in
	Linux)
	SERVER_OS="linux"
	;;
	*)
	echo "Error platform not supported: $PLATFORM"
	print_install_results_and_exit 1
	;;
	esac

as you see the output - which is empty in your case - is the result of uname -s and there are known issues with that on NixOS - you even have a package to solve this issue: https://mynixos.com/nixpkgs/package/deterministic-uname I guess that as soon as you install that the setup will work... or you possibly need the coreutils package...

But... what is the result if you execute the uname binary? And what is the output of echo $OSTYPE?
