Yes.  Without the "add" step, detecting the K92iptables that has
been moved to an untracked S08iptables as rename looked like a magic
(read: bug) to me, and that was why I asked.

Aren't K92iptables and S08iptables the same script with

  case "$1" in start) ... start thing ...;; stop) ... stop thing ...;; esac

in it?

On Debian, these S/K files appear directly under /etc without
intermediate rc.d level, and they are symbolic links to real files
in /etc/init.d/, so extrapolating from that knowledge and with a bit
of imagination that some systems might keep copies of these files
instead of linking to the same thing, I would actually find it
desireable to call the move from K92iptables to S08iptables a
rename, rather than reporting a removal and a addition of unrelated
files.
