From fa961ce0463ebd738da875c3a6da8171373d7723 Mon Sep 17 00:00:00 2001 From: Eric Windisch Date: Thu, 9 Apr 2015 13:55:26 -0400 Subject: [PATCH] Wrap installer in a function This will assure that the install script will not begin executing until after it has been downloaded should it be utilized in a 'curl | bash' workflow.
