Issues with WSL and mounted file systems

[lapplislazuli]

Hey,

not really an issue, but you might want to make a note of it.
I tried to use nix with ghc.nix on a WSL-shell.

When running in a mounted file system (e.g. my normal Windows user repo) I got issues with compilation, different ones each time.
This was simply fixed when using a wsl-native directory and not the mounted.

Might a short note for WSL users is good somewhere, took me a while to figure it out.
