Sorry, a bit late responding.
It's been a while since I did this but IIRC I booted the mac with
xubuntu live cd. Then I nfs mounted /opt/lstp. And then built the
client chroot.
The trickier part was getting the macs to boot from what the dhcp
server returned -- which this list was very helpful in solving.
I'll attach my test setup's dhcp that works with my Macs.
I'd welcome comments explaining what some of the config options do.
Oh, also it seems as if lts.conf is fetched from a different location
for the powerpc. I have a single lts.conf symlinked. Wireshark was
helpful to track that down.
