Not sure. I think the use of ACPI as to and will greatly increase in t

Yes, that is definately where I want to go evetually.
But, for the last_boot_normal this one bit toggles on every boot,
assuming one reboot per second a 100k writes flash chip is destroy

Possibly. But ACPI is running very early in the game. Where would we
hook it up?
This would also establish ACPI as a pretty hard requirement. There

What about writing to flash instead? IIRC some factory BIOSes

It definitely is, since linuxbios itself has no shell or
I think the key thing that v2 missed was in letting linuxbios set the
'boot success' flag. That flag should only be set by a payload or even
linux. It's not really useful to know that linuxbios came up. What
matters is that the payload came up. It was a big headache to me, esp.
on 1000 nodes, when

with v3 we can potentially have n:m mappings for all modules. is a

How should this work in V3? The current implementation doesn't really
make sense to me. See do_normal_boot() in V2.
I think that stage0+1 is the equivalent of V2 failover.
In stage1 the normal boot flag cmos byte is checked to see if the normal
or the fallback image should be loaded.
The cmos b
