Interactive Shell Vs Proper Root topic

Hi guys

Something slightly concerning, when rooting with the 4.3 upgrade, it doesnt actually provide full root.
Things like adfree, etc etc do not retain their root functionality. Because of the "interactive shell" only, this is the cause.
Any idea to set it to run with full SU permissions?
