[Casper] Erasing the Hard Drive During Imaging while Netbooted

[Ryan Harter]

I had similar issues because the "Diskless" option was not turned on  
in Server Admin.  Unless you specify Diskless, NetBoot will use the HD  
for shadow files and the like, and you will be unable to mount it  
because it is in use.  If you force unmount it then the netboot image  
doesn't work properly.

To fix this we just went to Server Admin > NetBoot > Settings > Images  
and check the Diskless option for the image in question.  This solved  
our issue.
