Nope. Your environment is being reloaded in the `sudo` process.

`sudo echo $PATH` gives the same result as `echo $PATH` because `$PATH` is expanded by your shell first thing, before `sudo` gets spawned. If you want to see the value of `PATH` from inside `sudo`, run `sudo bash -c 'echo $PATH'` instead.
