Let's not forget that installboot is used by sysinst.

"Partition 0" implies you have a boot partition in the Apple 
Partition Map.  AFAIK the only way we have to create those is with 
installboot.  AFAIK installboot still cannot leave an existing APM in 
place so you wind up with a BSD-partitioned disk and a fake APM that 
only supports OF booting.

It depends on whether you have an OF 1.0.5 machine like the 7300, or 
an OF 3.x machine like a G4.  The above APM would be the right way to 
do it with an OF 3 machine.  What you say is the way we support 
native booting on an OF 1 machine.  For an OF 3 machine you would put 
ofwboot.xcf in the HFS partition and tell OF to boot it directly with 
"boot hd:4,ofwboot.xcf ...".

Don't ask me about OF 2.x.
