Capistrano using sudo even with "set :use_sudo, false"

Question

I do not wish to use sudo for any of my remotely executed commands via Capistrano. Specifically, when I run cap deploy:setup, I'm asked for my sudo password during the first mkdir command. I added set :use_sudo, false to my deploy.rb file, but this did not make a difference.

I started with a fairly complete deploy.rb file, but whittled it down once I started having issues. Here is my minimal version that still shows use_sudo not being respected:

# App Definitions

set :domain, '[server-ip]'
role :app, domain
role :web, domain
role :db, domain, :primary => true

set :user, "my_app"
set :use_sudo, false

task :sudo_test do
  run "#{try_sudo} whoami"
end

running cap sudo_test results in me being prompted for my sudo password. What am I missing here (besides the hair I've already pulled out)?

For anyone else who runs into this issue and is a fool like me. Make sure you arn't quoting false. I had:

set :use_sudo, "false"

and when I switched it to

set :use_sudo, false

most things started working the way I expected. As YWCA Hello points out there are still commands that ignore the use_sudo setting. However, don't forget to set it correctly.
