Bug#375505: yaboot-installer: generated yaboot.conf is broken on IBM POWER hardware ...
clone 375505 -1 -2
reassign -1 yaboot
retitle -1 yaboot: ofpath fails on IBM JS21 blades
retitle -2 yaboot-installer: should write hvc serial console into append= line
retitle 375505 yaboot-installer: should only write magicboot= on NewWorld PowerMacs
thanks

I've cloned this to a yaboot bug, because apparently ofpath failed. If
you could give that cloned bug (I don't have the number yet, of course)
more details of the disks on this system and what the Open Firmware path
should be, then perhaps ofpath can be fixed.
That said, there's obviously no point in writing out an unparseable
configuration file, so I've changed yaboot-installer to avoid doing
this.

Fixed in r38733 (and will be in yaboot-installer 1.1.7), thanks.

OK, seems sensible. I have a patch for this, which I'll commit once I
get the cloned bug number back from debbugs.
