I have the following `chef` recipe to write some data to a file in the `current` user's home directory. As you can see, `vagrant` user is hardcoded in my case. What do I have to do so that the code gets the `user` dynamically based on who is currently logged in?

```
file '/home/vagrant/.ssh/id_rsa' do
  content "This is the super secret"
  mode '0755'
  owner 'vagrant'
  group 'vagrant'
end

```

I tried doing something like the following but it does not work:

`file '/home/#{node['user']}/.ssh/id_rsa'`
