+1.  The cause of XWALK-1074 is current codebase for Tizen installation(by '$ xwalk --install') doesn't work after we migrate to IVI, because application installation is under 'app' mode now, not the 'root' mode on Tizen Mobile. And this needs more investigation to make both 'root' mode and 'app' mode work on IVI.
I think this patch is ready as an urgent fix.
