Could you explain me this God script?

[Alfredo Motta]

Hello everyone,

I have a plain Ruby app that needs some Resque workers in the background.

To monitor the workers I installed god for the root user (because I was not able to do differently).

This is the god script that monitors the workers.

My source of confusion is the following. I now have two ruby environments:

/root/.rbenv/

and

/home/my_user/.rbenv

Under the rbenv of my_user I have the resque gem

/home/my_user/.rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/resque-1.25.2/

But under the rbenv of root I don't

ls .rbenv/versions/2.2.0/lib/ruby/gems/2.2.0/gems/

bundler-1.8.0/      god-0.13.5/         minitest-5.4.3/     power_assert-0.2.2/ rake-10.4.2/        rdoc-4.2.0/         test-unit-3.0.8/

What happens when I run bundle exec in the god script ?

Which ruby environment is loaded ?

I was expecting this script to fail, but it's actually working and I don't understand how it's possible.

Thank you for your help,

please let me know if I can provide more informations to clarify my doubt.
