Any Darwin 8.x BootX should be able to boot any Darwin 8.y kernel for
x!=y (and x==y).

Hi,
because "it ought to be possible", I wanted to boot my G4 PowerMac
from a filesystem built entirely with open source components from
darwinsource. This works (well, it doesn't, the kernel panics
straightaway. But I know how to fix that), although because I
hadn't realised how to configure the secondary bootloader (read:
hadn't RTFM in the bless project), initially copied /System/Library/
CoreServices/BootX from a working OS X installation. This worked,
although the OS X and the Darwin were different minor versions.
I've since generated a new BootX from the usr/standalone/ppc/
bootx.bootinfo on the Darwin disk.
So, the question would be: how different would two Darwins have to
be before the secondary bootloader on one won't bootstrap the other;
or could a BootX generated from bootx.bootinfo on *any* Darwin boot
any Darwin (or even any old mach_o-shaped kernel with the correct
jumping-on point)?
Cheers,
Graham.
