[chef] Problem with deploy_branch

[Jenn Fountain < >]

Here is the recipe I am having problems with:


  deploy_branch node[:app][:frontend][:directory] do
  repository node[:app][:git_repository]
  ssh_wrapper node[:app][:git_ssh_wrapper]
  branch node[:app][:branch]
  enable_submodules true

  user 'app'
  group 'nginx'

  create_dirs_before_symlink.clear
  purge_before_symlink %w{log}
  symlink_before_migrate.clear
  symlinks({'log' => 'log'})

  action :deploy
end

It is creating a copy of repository_cache but seems to be keeping older files 
and causing code conflicts and issues.   I am running nginx and php_fpm.  

Is anyone aware of any issues with what I am doing or is there an known 
issue?  Anyone to disable repo_cache?

Thanks for any help!
