Support for ghcup in NixOS
What's the current status of ghcup in NixOS ? Is it a supported tool for NixOS distribution ?
I did try to use it, but it didn't work in my attempts:
[nix-shell:~]$ ghcup install ghc 8.10.5

Check the logs at "/home/sibi/.ghcup/logs" and the build directory "/run/user/1000/ghcup-edCqO9" for more clues.
Make sure to clean up "/run/user/1000/ghcup-edCqO9" afterwards.Other tools like rustup is working fine in NixOS, so probably NixOS isn't supported now ?
