/etc/inittab allows commands to be differed by runlevel (i.e. do this in
runlevel 3, do that in runlevel 5) but not by user. What you can do
instead, however, is add the -a option to the shutdown command in
/etc/inittab:
In inittab, change the line that says
ca::ctrlaltdel:/sbin/shutdown -t3 -r now
to say
ca::ctrlaltdel:/sbin/shutdown -a -t3 -r now

Well, I suppose if you have a really, really, really old version of init,
it might not have had the Ctrl-Alt-Del catch implemented yet, but If
you're using Mandrake, Debian, RH, SLackware, whatever, it will work just
the same. As to shutdown, well, every distribution had damn well better
include it- you can't safely shut down the machine without it!

P.S. Is "differed" really a word?
