[mrtg] Re: UNIX/Linux startup script, anyone??

[Michael Marziani]

I figured I'd write one.  I took a "skeleton" script that was in my
/etc/init directory and did a good bit of modifying.  The fact that MRTG
creates it's own PID file is nice, but it will depend on where you
install MRTG where the PID file will be.  I put all the variables that
might need modification right at the top.  Hopefully this will work for
everyone.  Comments are welcome.
