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.

A temporary fix is to comment out the check and error message in /usr/sbin/ofpath (Line 710 to 715). matt@daubenspeck.org 2005-10-06 12:27:04 0000 I tried that, but since /usr/sbin/ofpath is on the boot CD, it's read-only and cannot be saved. dostrow@gentoo.org 2005-10-08 16:59:02 0000 Fix in CVS dostrow@gentoo.org 2005-10-08 17:52:01 0000 Whoops...forgot to close it. wolf31o2@gentoo.org 2005-11-21 06:51:19 0000 This is fixed with the 2005.1-r1 release media.
