MDK,
This is not universal. The shut-down process need not
be routed through the "shutdown" command per se. It is
possible to close down using halt which is normally not
a symlink, and in most distros a seperate elf binary.
Both these however, are designed to execute the run-
level 0 scripts. That is the place where additional bits
can be put. The problem is the location of the shutdown
(runlevel 0) scripts is distro specific. Under BSD style
distros, the file to tackle is /etc/rc.d/rc.0 which in
some distros may be symlinked to rc.6. Under Sys-V type
distros, the location is normally the K files within the
/etc/rc.d dirs. You need to know your distro quirks, if
you need to go about adding to shut down scripts.
Nothing is needed to be changed at /etc/inittab level
unless you want to change the three-finger-salute from
the default reboot to halt.
