How would you switch from the old/current devenv to this rewrite?

I'm getting

$ nix profile install --accept-flake-config tarball+https://install.devenv.sh/rust-rewrite
[0/1 built] Segmentation fault

@sneakyvv Works for me:

flake.nix

inputs = {
    devenv.url = "github:cachix/devenv/rust-rewrite"; # (i) https://github.com/cachix/devenv/pull/1005
};

Could you give more information what system you're running this on?

I'm running it on WSL2, and got it working by running nix profile install --accept-flake-config tarball+https://install.devenv.sh/rust-rewrite from a folder where I also added the needed devenv.yaml config (as stated in description of this ticket).
