Yes. Weird. I wonder what the purpose is.
It's just a matter of taste. Since a shell script exits with
the status of the last command executed, and the exit value
of ":" is always 0, "exit 0" and ": exit 0" at the end of
a shell script are functionally equivalent.
I tend to use ": exit 0" at the end of a .sh script because
the .sh scripts are sourced, and exit 0 might also exit the
calling shell script. ": exit 0" just makes that more
explicit.
Since /etc/init.d/rc call the .sh shell scripts in a
seperate environment using ( .. ) this cannot happen, so
I could just use "exit 0" (or no exit at all), but still,
it doesn't really matter.
