Package: yaboot
Version: 1.3.16-4
Severity: important

Dear Maintainer,

ofpath returns the wrong result, causing the /etc/yaboot.conf file to have an
unbootable device path. I encountered this while trying to install Jessie on
a Powermac G5.

Here is the wrong output (from my now-booting system):

  $ /usr/sbin/ofpath /dev/sda2
  /ht at 0,f2000000/pci at 9/k2-sata-root at c/@ffffffffffffffff/@0:2

I would expect the output to look something like:

  /ht at 0,f2000000/pci at 9/k2-sata-root at c/k2-sata at 1/disk at 0:2

instead. It looks like the "@ffffffffffffffff" part comes from some commanad in
ofpath returning -1. The last part "@0:2" might be wrong too.

(note: I was only able to boot the system by replacing the device line in
 yaboot.conf to be "device=sd1:")
