Hi Stef,

Your more precise instructions including the "runit" script got me 
through step 3. I confirmed that it's broken with logs at 6 and works 
with logs at 7. Now I'm stuck at step 4. What file contains the lines to 
be changed? I grepped and found several files that contain these 
strings. I guess I need more precise instructions, but I'm confident I 
can follow them.
