Can't read logfile option in config file

[h3poteto]

I can't work fine, for example:

rails@085a8fd8cf4a:~/app$ bundle exec shoryuken -R -C config/shoryuken.yml -d
You really should set a logfile if you're going to daemonize
/home/rails/app/vendor/bundle/ruby/2.3.0/gems/shoryuken-2.0.11/lib/shoryuken/cli.rb:80:in `daemonize'
/home/rails/app/vendor/bundle/ruby/2.3.0/gems/shoryuken-2.0.11/lib/shoryuken/cli.rb:34:in `run'
/home/rails/app/vendor/bundle/ruby/2.3.0/gems/shoryuken-2.0.11/bin/shoryuken:6:in `<top (required)>'
/home/rails/app/vendor/bundle/ruby/2.3.0/bin/shoryuken:23:in `load'
/home/rails/app/vendor/bundle/ruby/2.3.0/bin/shoryuken:23:in `<main>'

In shoryuken.yml, I wrote logfile option:

verbose: false
concurrency: 20
delay: 25
pidfile: ./tmp/pids/shoryuken.pid
logfile: ./log/shoryuken.log

but shoryuken didn't read logfile option.

I expect this case occur after #219.
EnvironmentLoader.load read config file, and initialize logger. And daemonize check Shoryuken.options[:logfile]. So, if call daemonize before EnvironmentLoader.load, daemonize fail.

Current shoryuken source code,
https://github.com/phstc/shoryuken/blob/v2.0.11/lib/shoryuken/cli.rb#L32-L39
call daemonize before EnvironmentLoader.load, so didn't read logifle option in config file.

At the same time, I understand #219 is required.

In sidekiq, read config file options and initialize logger, before daemonize.
https://github.com/mperham/sidekiq/blob/v4.1.2/lib/sidekiq/cli.rb#L39-L43

I thought that call initialize logger before daemonize in the same manner as sidekiq, but shoryuken have to load Rails before read config file: #197
therefore I can't fix.

What do you think?
