Chef - Dir.exists? guard treating symlink as directory

I have a recipe which deletes an empty logs directory, then replaces it with a symlink in the next step. 

directory "#{ENV['GS_HOME']}/logs/" do
  action :delete
  only_if { ::Dir.exists?("#{ENV['GS_HOME']}/logs/") }
end

It works the first time around but on the next chef-client run when it should not delete the item which is now a link to another directory, I receive an error:

Errno::ENOTDIR
--------------
Not a directory @ dir_s_rmdir ...

Why does the guard appear to treat the link as a dir and not skip, but then the resource action recognizes it correctly, not as one, and fails? What is the best way around this?

The first time, the guard checks if it's a directory. Consequent run it can check if the file directory is a symlink. Try

directory "#{ENV['GS_HOME']}/logs/" do
  action :delete
  only_if { ::Dir.exist?("#{ENV['GS_HOME']}/logs/") || !::File.symlink?("#{ENV['GS_HOME']}/logs/") }
end
