Installs being dropped straight into a busybox shell

[Tim Edwards]

I'm trying to install etch from an FAI CD image but am not having much 
luck. I got past one error by adding live-initramfs as instructed at 
http://faiwiki.informatik.uni-koeln.de/index.php/FAI_3.2_Usage_Changes 
but am now just having the installation drop into a busybox shell almost 
straight after starting. I have a screenshot if necessary. The prompt in 
the shell is "(initramfs)", I'm really not sure what's going on here?

Thanks
Tim
