Defined in:

Overview

Using ‘lazy {}` within a resource guard (not_if/only_if) will cause failures and is unnecessary as resource guards are always lazily evaluated.

Examples:


### incorrect
template '/etc/foo' do
  mode '0644'
  source 'foo.erb'
  only_if { lazy { ::File.exist?('/etc/foo')} }
end

### correct
template '/etc/foo' do
  mode '0644'
  source 'foo.erb'
  only_if { ::File.exist?('/etc/foo') }
end
