Custom Partitioning screenshot

http://ppc.koji.fedoraproject.org/stage/21_Alpha_TC3/Server/ppc64le/iso/Fedora-Server-DVD-ppc64le-21_Alpha_TC3.iso

anaconda-21.48.6-1.fc21.ppc64le.rpm
python-blivet-0.62-1.fc21.noarch.rpm

Fedora 20 installed with the following snippet of a kickstart file

8<---8<---
# Format the drives
clearpart --all --drives=sda,sdb --initlabel

# Disk partitioning information
part prepboot0 --size=8 --fstype=prepboot --asprimary --ondisk=sda

part raid.10   --size=8 --asprimary --ondisk=sdb
part raid.11   --size=33000 --grow --ondisk=sdb

# RAID setup
raid pv.00 --level=RAID1 --device=prep --fstype="prepboot" raid.00 raid.10

# System bootloader configuration

Only the prepboot partitions and the broken LVM on sdc show up in the custom partitioning sreen.
