Not good :-(
Which daily image did you use exactly. You may need to use a netboot
image to really get the latest mountmedia. I'm not sure how the daily
cdroms images are currently built. They may be built with the beta1
installer. Please verify that you have mountmedia 0.21 on your
installation medium.
This image contains mountmedia 0.21:

The bug I mentioned happens every time mountmedia is run. The
installation report also reports two hangs earlier during installation.
#684293 is the corresponding bug in the linux kernel which is the root
cause of the issue I suspect to be your problem.

As Milan pointed out this is harmless.

So it seems that at least some part to make the partitions work is
missing before hw-detect. You could compare the list of loaded kernel
modules. But I'm not sure if this is really relevant because after
hw-detect at least /dev/sda2 is fine.

I think that's the important part. This is exactly the same behavior as
in the two bug reports I mentioned. The fix in mountmedia skips
partitions we know to hang. This leaves to posibilities. Either your
image does not have the fixed mountmedia or the fix is not correct for
powerpc (apple partition tables). What does
blkid -p -s PART_ENTRY_TYPE /dev/sda1 | cut -d ' ' -f 2 | cut -d \" -f 2
report? In mountmedia we currently skip tpyes 0x5 and 0xf. Maybe another
type has to be skipped for apple partition tables. If your partition
type is different you can modify /bin/mountmedia with nano and add your
partition type to the list of types to avoid.
