I forgot to Reply All, so I apologize to Philipp for the double post.
Sorry, a typo on my part, it should create any parts of TEXMFVAR (NOT TEXMHOME) that don't already exist. E.g. on the Mac TEXMFVAR is ~/Library/texlive/2013/texmf-var but ~/Library/texlive already exists since I also have TL2012 so 2013/texmf-var needs to be built. For new users the complete path needs to be build. All this should be transparent to the user.
