How do I use grubby to set a kernel to boot once then reset to

Previously I did this on FC 5:
echo "savedefault --default=1 --once quit" | grub
grub.conf:
default saved
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title FC (2.6.18-1.2239.fc5smp)
root (hd0,0)
kernel /vmlinuz-2.6.18-1.2239.fc5smp ro root=/dev/rootvg/rootlv01
initrd /initrd-2.6.18-1.2239.fc5smp.img
savedefault
title Power Off
savedefault --default=0
halt

Hi fuzzie1300,
I would probably find a good place in the shutdown process, test for
the use of the onetime kernel and then have it swap out
/boot/grub/grub.conf with one pointing to the new kernel. Since it
looks for the use of the old kernel it would never execute again, as
if that mattered.
Good Hunting!
