You will go into single-user mode if "-h" or "-r" is not annotated with the shutdown options. Putting "-ar" or "-ah" will actually halt or reboot, instead of going into single user mode. A cleaner option would be to use sudo as suggested by the earlier posts on this thread. This way one may disable the 3-finger-salute for all through inittab ... The man pages of sudo is a bit terse, and the sections User_Alias and Cmnd_Alias are not very clear. You may have a look at http://geocities.com/usmbish/hdi.html.
