+# This Kickstart snippet checks the first two hard drives in the system.
+# If they are the same size, then it tries to build a RAID-1 mirror on
+# them. If it can't, then it creates a /boot and a LVM arrangement.
+#
+# By default I create a 1G swap and throw the rest in /. Because I've been
+# carting this around since RHEL4 days, it refers to ext3. Of course all
+# of this is changable.
+#
+# For some reason it doesn't work on C7.
