[ale] OT: how to reset root pw on os X

[timtw at earthlink.net (Tim Watts)]

Hi,

I have an artist friend with a bunch of OS X machines who can't remember his 
root's password. His user account has admin privileges and so has never 
needed it. 

Does anyone know how one would do this? On SuSE I would boot off a CD, go into 
rescue mode and tinker with the shadow passwd file. Does OS X have a similar 
thing?

His network is not set up to allow me to ssh into his systems so any 
step-by-step details anyone could provide would be most appreciated.

Thanks.
