How to make configuration changes without a reboot?

[Matthew T. Lager]

You can do a shutdown now to get to single user mode, then execute an exit
which will boot back into multi-user mode. All rc scripts will be
re-initilized and you won't have to reboot the entire system (be sure to
only do this on the console obviously)...
