I'd love to find something like that.  I reboot from one kernel
to another pretty frequently, and it's a PITA to have to sit
there and watch the machine while it shuts down so that I can
catch GRUB or LILO at the right time and pick the right kernel.

I inevitably have to answer the phone or something and miss my
chance to pick a kernel.  So, I end up having to wait while the
default kernel boots up so I can shut it down and try again.

It sounds trivial, but when you do it 8 or 10 times a day it
eats up a lot of time.

It would be great to be able to do something like:

 # shtudown -f -r -k <what-to-boot> now

And then be able to come back a few minutes later and have the
new system up and running. 

I suppose one could do it by shuffling GRUB menu.lst files
around, but that sounds messy.
