Use `exec` to invoke `foreman` to make sure `bin/dev` is replaced by the `foreman` process. This ensures that `foreman` gets `bin/dev`'s pid (so it's cleaned up properly) and that interrupts and signals (like `ctrl+c`) are handled correctly by `foreman` (to shut down child processes).
Some distros don't ship with bash, but will have sh. see also: rails/cssbundling-rails#98
