[Debootloaders-yaboot] Bug#589701: ofpath is not compatible with non-builtin disk controllers

[Benjamin Cama]

Hi Rick,

I am a bit disappointed about how this is ending, but I just realized
you are using an addon Promise card as disk controller. This is not
supported by ofpath, which just handle IDE controllers using the old ATA
stack or true SCSI controllers. In short, it is hardwired for a list of
disk controllers.

Your bug is a bit different from #572869, even if he's also using a SATA
(so, new ATA stack) controller, but this is the Apple provided one, and
yaboot has a special case for it (even if it seems not to work so well
for now).

I don't really know what to do about that. From what I read (#372186),
ofpathname is better for recent controllers using the new ATA stack, and
it's what grub2 is using. Still, it may lack proper handling of old
controllers, even if we can see (again) people willing to bring that
from ofpath, without much result.

Furthermore, since 2.6.34, benh wrote a new driver (macio) for newworld
Macs (I don't know if it supports /all/ machines) that is based on the
new ATA stack, so ofpath will need to support it soon (well, it's for
after squeeze at least), or we'll need to switch to ofpathname (or grub2
alltogether).

Anyway, thanks for your perseverance, but try to be more specific on
your problems next time ;-)
