[chef] Berksfile question

[Mark Pimentel < >]

If I specify a git location without a branch and the metadata.rb specifies the version required, does berkshelf pull master and check the version in that dependencies' metadata?

If I want to pull a specific tag, I understand you would have to specify branch: "1.0.0" in berks but then also in metadata?  That seems somewhat redundant.  

Am I missing something?
