Dual Boot on a PS3

[John Frankish]

Hi,

I'm using ydl-6 on a playstation 3 and would like to set up a dual 
boot using yaboot.

The ps3 has the default ydl-6 partitioning:

ps3da1 = boot (or bootstrap?) partition
ps3da2 = root partition
ps3da3 = swap

I've compiled a cross linux-from-scratch build under /clfs on ps3da2 
and would like to modify yaboot.conf to be able to have the option to 
boot from /clfs - note that clfs uses /clfs/sbin/pre-init to take 
care of the fact that the build is not under the root ("/") directory.

Is it possible to modify yaboot.conf to achieve the above? I don't 
have much experience with ppc/yaboot (as opposed to x86/grub) and the 
yaboot.conf below doesn't work for clfs, but does work for the 
kernels on ydl-6.

Any suggestions would be most welcome.

John
