after running the installer on a PowerMac G5 no root filesystem found

[Dennis Clarke]

Not sure if this is a bug in the installer or what but I can tell you
that the installer seems to do what it says it will do.  I boot a G5
with the latest 12.0b4 installer dvd and go through the usual motions
wherein I select a whole disk auto ufs install and allow the installer
to do whatever magic it does for an Apple type partition.  Every other
type of partition results in a popup message that simply says this
platform can not support or boot or grok this partition. So I go with
the Apple type. Nothing else fancy here.

At first boot I get a load of text and then a strange prompt that seems
to be asking where is the root filesystem? It also lists all the various
filesystems found. I tried to enter ufs:/dev/adas2 and similar things
but this gets me nothing but an unrecognized filesystem message.

So .. something obvious?
