I'm assuming you mean the script in the telnetd package???
That's the only one I can think of that I wrote...

All it does it create some extra device files in /dev/ which are used for the telnet daemon. They're harmless and won't affect anything else.

The files it creates are ttyp0 to ttypf and ptyp0 to ptyf. You can get rid of them if you don't want the telnet daemon.

If you're talking about the big script at the top of this thread to setup preinit then that's nothing to do with me Ask genixia
