Specifically, http://cdimage.debian.org/cdimage/daily-builds/sid_d-i/arch-latest/powerpc/iso-cd/debian-testing-powerpc-netinst.iso Daily build #3 for powerpc, using installer build from sid This build finished at Fri Aug 17 09:39:24 UTC 2012.The first problem noted in bug#684265 is still there -- the installer still does not put the existing root partitions into the generated yaboot.conf.
When I installed os-prober and ran it on the installed system, it found and listed the existing root partitions, as expected. So the problem is in the installer, not os-prober...
The other problem noted in bug#684265 -- The installer was not commenting out the "deb cdrom" line for the installer CD -- has apparently gone away.
Attached is a (hopefully) relevant extract from the installation syslog file.
