Autostarting Servers and Process.. with inittab

So everyone seems to have forgotten that /etc/inittab is a great place to keep your daemons running. Not me. Here is how to keep sshd (s-s), named, mysql, and apache always on using /etc/inittab. The difference is awesome when you do a ps Aux or a pstree.

Check it out! This lets me run named with only 3 child processes, lets me run mysql with it's mysqld_safe wrapper, and even lets me run apache with some custom ulimit settings. Goodbye chkconfig, ntsysv, all that junk. This is the down and dirty.
