+Author: Doug Freed <dwfreed@mtu.edu>
+Commit: William Hubbs <w.d.hubbs@gmail.com>
+
+    rc: remove use of magic constant and allow OpenVZ to drop to shell
+    
+    OpenVZ has had console support for a long time now; allow them to use it
+    to drop to a shell during interactive boot.

+
+    librc: handle rc_sys="prefix" even if we weren't built with a prefix
+    
+    This probably isn't needed, but it mimics old behavior.

+
+commit 04d94be766ae2808adc709b0e4e03ce1f3a75d5d
+Author: Doug Freed <dwfreed@mtu.edu>
+Commit: William Hubbs <w.d.hubbs@gmail.com>
+
+    librc: move system detection code into rc_sys and use it
+    
+    This fixes an issue where librc code was calling code that only existed
+    in the rc binary.
+    
+    This reverts commits 8addd79 and 9f6e056
+    
+    This fixes #75.
