dir interpolation from hydra into job config is not working

See original GitHub issue

I can set the second_dir from base_dir, but output_subdir can not in this case.

experiment:
  base_dir: ???
  second_dir: ${experiment.base_dir}
hydra:
  output_subdir: ${experiment.base_dir}/.hydra

KeyError: "str interpolation key 'experiment.base_dir' not found"

Is there any way I can change the hydra config based on current .yaml or some alternately way?
Thanks!

For posterity: I needed ${hydra:runtime.cwd} rather than ${hydra.runtime.cwd} in order to get interpolation to work.

By the way, the next version of Hydra will also have a variable: hydra.runtime.cwd which will hold the current working directory you launched your app from, so you will presumable be able to do something crazy like:

hydra.run.dir: ${hydra:runtime.cwd}

Although I did not test it. If you want to try install Hydra from master.
