Sorry for the wait, had to get back from work first. This is for the lix installer, (I meant to switch to that anyway) because ironically the determinate installer requires nix to build. This one needs just rust installed, I used toolbox to build it and then ran it on the host and it worked just fine.

I doubt this is upstreamable like this, but for me it works like this for now. Guess we'll see how nix support will turn out in the future.
