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.
