remote control dual booting OSX / Debian

[Rich Johnson <rjohnson@dogstar-interactive.com>]

I've found these two scripts useful for remotely switching between  
os's on a dual-boot new-world mac.   The scripts require a sudo  
environment.  They run from the command line, and do not require  
access to the system (yaboot) console.

After the scripts are two aliases I use to have a fool-proof, not- 
parameterized command.

Would anyone care to comment?

Debian version:  usage "sudo reboot-from <partition>"
reboot-from:
    $! /bin/sh
    nvsetenv reboot-device hd:$1,\\\\:tbxi
    shutdown -r now

OSX version:  usage "sudo reboot-from <partition>"
reboot-from:
    $!/bin/sh
    nvram boot-device=hd:$1,\\\\:tbxi
    shutdown -r now

I use the scripts with the following shell aliases (my partitions are  
OSX on 10 and Debian on 13:
Debian/bash:
  function boot-osx () {
      sudo reboot-from 10
      }

OSX/tcsh:
  alias boot-linux sudo reboot-from 13
