TIme Machine Broken (UUID not unique?)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Back up two netbooks to the same time capsule.
2.The machines will get confused, and start using the same backup
3.

What netbook are you using this on?
2xmini9

What is the expected output? What do you see instead?
Each should back up to it's own sparsebundle. They can be persueded to CREATE 
their own 
bundles, but they then start using the same one. If one already exists the 
second machine will 
use it rather than making its own.

What version of the product are you using? On what operating system?
0.8.3 final/10.6.2

Please provide any additional information below.

Inside the sparsebundle is the file "   com.apple.TimeMachine.MachineID.plist"
which contains the hostUUID. These are the same for both machines (as per 
System Profiler). It 
looks like Time machine uses the UUID to identify which backup belongs to this 
machine and as 
the UUID is no longer unique it uses the wrong one.

There are some kexts to modify the host UUID. I don't know if these could be 
used to fake the 
serial number into a pseudo UUID - it dosn't need to be REALLY unique. Just 
unique enough that 
it's not going to clash.

I can confirm this problem.  I have a Vostro A90 and Mini 10v.  Both are on the
latest NBI and 10.6.2.

Confirm. Samsung NC10 and Lenovo S10e.

Is there any way to change this manually?
