Configuring the root account to use BASH
Its a good idea to to keep the root account configured to use /sbin/sh for compatibility and redundancy.
However the bash shell is more user friendly, what we can do is set the root user profile to only use the BASH shell
if it is available, otherwise use the regular shell.
All you have to do is edit .profile and add these lines,
if [ -f /usr/bin/bash ]
