12.04 DVD install crashes if software raid partitions are present
When installing from the DVD (12/30/2013 version) the installer will fail to intramfs if there is a software raid partition on the computer.
casper.log begins with "chroot: can't execute 'mktemp': no such file or directory" and continues with many file not found messages.
Workaround: boot into kubuntu alternate installer, remove all software raid shenanigans.
