Error partitioning with RAID

[Diego Zuccato]

Hello all.

I'm having issues trying to create a layout from scratch.
I used the RAID example to write this:
-8<--
disk_config disk1 bootable:1 preserve_lazy:3,6
primary	-	200M	-	-
primary	swap	2G	-	-
primary	-	120M-122M	-	-
logical	-	15G	-	-
logical	-	10G	-	-
logical	-	1G-	-	-

disk_config disk2 sameas:disk1
disk_config disk3 sameas:disk1

disk_config raid fstabkey:uuid preserve_lazy:3,6
raid1	/boot		disk1.1,disk2.1,disk3.1	ext4  rw,noatime,errors=remount-ro
raid1	-		disk1.3,disk2.3,disk3.3	ext4  noauto createopts="-L PERMDATA"
raid5	/		disk1.5,disk2.5,disk3.5	ext4  rw,noatime,errors=remount-ro
raid1	/var/lib/mysql	disk1.6,disk2.6,disk3.6	ext4 
rw,noatime,nosuid,nodev,rw
raid5	/home		disk1.7,disk2.7,disk3.7	ext4  rw,noatime,nosuid,nodev,rw
-8<--

The first issue is that I have yet to grasp the difference between 
preserve_reinstall and preserve_lazy. But at least when there's no 
partition table and flag_initial=1 it seems preserve_reinstall errors 
out (cause it can't read the partition table) while preserve_lazy allows 
to continue.

But now it errors out:
-8<--
INTERNAL ERROR in setup-storage:
filesystem is undefined
Please report this error to the Debian Bug Tracking System.

Any hints?

Tks.
