I have almost never logged on to my system as root. I just log on as a user, and if I need to install anything i just do
Or, for instance, i want to modify a configuration file that only root has access to, such as the grub.conf i would do something like
su --command="gedit /boot/grub/grub.conf"
I prefer to do things using
su --command="blah blah blah"
when I only want to run one command as root so I don't forget I have root authority and screw something up.
