I was just trying to give an idea about what it's for, and I assume he's
not using, as he's not complaning that "my copy of XXX that I payed $$$
for isn't working anymore".

I have looked, and on my (Red Hat) box, it's loaded in
/etc/rc.d/rc[235].d/S<priority>ibcs, which are all symlinks to
/etc/rc.d/init.d/ibcs. I don't assume that all Linux boxes are the same,
you shoulden't either.

Yes, I was only trying to give an _idea_ of that what it does, not an
exhaustive list of capabilities.
