A check in ofpath makes it bail out without returning any path (only for /dev/sd* arguments). So ybin and brethen will fail to run properly. This is manifest only in the 2.6.12 kernel series, and is caused by a /proc/device-tree cleanup as mentioned at <http://lists.penguinppc.org/yaboot-devel/2005/yaboot-devel-200506/msg00055.html> The above URL also offers a fix, which has been deemed correct only if BootX is no longer in use (cf. <http://lists.penguinppc.org/yaboot-devel/2005/yaboot-devel-200506/msg00056.html>). Since the yaboot-static package is ppc64 only, and ppc64 cannot use BootX afaik, I believe that applying the patch is in order. Reproducible: Always Steps to Reproduce: 1. Boot any 2.6.12 kernel 2. Run ofpath /dev/sda (or similar or something that uses ofpath such as ybin) Actual Results: < turing:~ > ybin -v ybin: Finding OpenFirmware device path to `/dev/sda2'... ofpath: /proc/device-tree is broken. Do not use BootX to boot, use yaboot. ofpath: The yaboot HOWTO can be found here: http://www.alaska.net/~erbenson/doc ybin: Unable to find OpenFirmware path for boot=/dev/sda2 ybin: Please add ofboot=<path> where <path> is the OpenFirmware path to /dev/sda2 to /etc/yaboot.conf ybin: Finding OpenFirmware device path to `/dev/sda11'... ofpath: /proc/device-tree is broken.

This affects standard ppc as well: # ofpath /dev/sda ofpath: /proc/device-tree is broken. Do not use BootX to boot, use yaboot. ofpath: The yaboot HOWTO can be found here: http://www.alaska.net/~erbenson/doc # ybin -v ybin: Warning: `nvsetenv' could not be found, nvram will not be updated ybin: Finding OpenFirmware device path to `/dev/sda2'... ofpath: /proc/device-tree is broken. Do not use BootX to boot, use yaboot. ofpath: The yaboot HOWTO can be found here: http://www.alaska.net/~erbenson/doc ybin: Unable to find OpenFirmware path for boot=/dev/sda2 ybin: Please add ofboot=<path> where <path> is the OpenFirmware path to /dev/sda2 to /etc/yaboot.conf Install halts at this point.
I've seen this problem, too. A temporary fix is to comment out the check and error message in /usr/sbin/ofpath (Line 710 to 715).
I tried that, but since /usr/sbin/ofpath is on the boot CD, it's read-only and cannot be saved.
Fix in CVS
Whoops...forgot to close it.
This is fixed with the 2005.1-r1 release media.
