lilo -R equivalent

Hello list,

The good old lilo had the option of a one-shot reboot into a different
kernel, for instance:

default: kernel-1
new: kernel-2

Running:

# lilo -R kernel-2
# init 6

reboots the machine into "kernel-2". If ever (especially on a remote
machine) "kernel-2" ends up in a panic or whatever, a simple power
cycle make the box boot into "kernel-1" again.

Question: does grub has such a "boot once into a different kernel"
option as the "lilo -R <kernel>" equivalent?

R.
