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.
So do you know more about this then the man pg?
From the init man page:
"The init binary checks if it is init or telinit by looking at its process
id; the real init's process id is always 1. From this it follows that
instead of calling telinit one can also just use init instead as a
shortcut."
Notice the part about the shortcut??
I have only been administering *nix systems for a short time (15 years)
but in that time I can tell you I have never typed telinit except in
response to statments like the above.
I have to wonder why telinit exists then. Did someone start using it in
scripts so that it got grandfathered and every subsequent Unix-like OS had
to keep a link to that name around? Or is the man page writer just making
an observation about the implementation? The fact that it checks the
process ID sounds like a defensive hack rather than a feature. It could
also have checked the ID and refused to run if it was invoked as "init".
