Just install fail due to ~/.nix-profile unwriteable

[shanecelis]

Problem

On the main branch, my just install failed because I had a ~/.nix-profile that was setup like this (not by me personally):

$ ls -ld ~/.nix-profile
lrwxr-xr-x  1 shane  staff  46 Oct  2 08:19 /Users/shane/.nix-profile -> /Users/shane/.local/state/nix/profiles/profile

Work Around

I removed that link and it worked.

Contributing Factor?

I had installed the official nix package before going to determinate nix.

I have a fix for this in my branch here: https://github.com/elodin-sys/elodin/pull/237
