On my FC5 install telinit is symlinked to init, so no odds in which gets
used.

Many programs are installed under multiple names this way, and the name used to launch the program tells the program what you want it to do. For example, sendmail is linked to mailq. When invoked as sendmail, it sends mail. When invoked as mailq, it lists the mail queue. But it's the same binary.

When your objective is to change the runlevel, you should invoke telinit. Future versions of the program may treat invocation as init to do something quite different.
