Comments/Problems:

Hi, many thanks for this wonderful installer. It helped a lot. I wanted a
not officially supported root-on-LVM-on-RAID setup, and it did warn about
this. The needed changes ARE small, but ...

Partition hard drives:
----------------------
Wishlist-list:
- make it possible to create a LVM PV on top of a RAID.
- Manage Raid-level 5 with mdcfg
Workaround: Go to the console and do
# sfdisk -uM /dev/discs/disc0/disc <<EOF
...
EOF
# sfdisk -d /dev/discs/disc0/disc | sfdisc /dev/discs/disc1/disc
and for all other drives
# modprobe md
# mdadm -C /dev/md/0 -l1 -n3 /dev/discs/disc[012]/part1
# mdadm -C /dev/md/1 -l5 -n3 /dev/discs/disc[012]/part3
or to your liking
# modprobe dm-mod
# vgscan
# pvcreate -ff /dev/md/1
# vgcreate -A n vg0 /dev/md/1
# lvcreate -A n -L 256 -n root vg0
and for all other partitions
Then continue with the partitioner normally (it needs to reread the
partition table).

Install base system:
--------------------
debootstrap at some point fails, because it cannot umount /target/proc.
I couldn't confirm this for sure, but probably, this is due to a running
mdadm -F process left over from automatically installing mdadm-1.6.0-1. Workaraund:
Edit /usr/lib/debootstrap/functions, in the function setup_proc make
these changes:
on_exit "umount $TARGET/proc/bus/usb || true"
+ on_exit "sleep 10"
+ on_exit "umount $TARGET/proc || true"
- on_exit "umount $TARGET/proc"
The sleep gives you a little time to kill the mdadm-process (see below)
and the "|| true" at the umount keeps the thing from failing (it does even
WITH a killed mdadm. I don't see, why).
To kill the mdadm, have this command running during the base installation:
# kline=""; while [ -z "$kline" ]; do
kline=`ps ax|grep -v grep|grep "mdadm -F"`;
done; kuid=`echo $kline|sed "s/ *([0123456789]*).*/1/"`;
kill $kuid
I umounted /target/proc by hand afterwards.

This is a dirty hack! For a better solution, find out, what exactly
causes the umount to fail in the script. If I do it by hand, it works
as long as the mdadm is killed before. But the script still fails, if
the "|| true" is missing... Why? For a better solution:
- debootstrap could try and find all processes using /proc and kill
them before the umount.
- All packages, that start demons, should not do so during debootstrap
(maybe set a defined config-entry debootstrap/installing ?)

Wishlist:
- if /boot is a RAID1 array, call grub-install for all of its drives.

Reboot:

As mentioned in bug-report #262092 for initrd-tools, vgchange does not work properly in the initrd. What happens seems to be:
On scanning /dev (if no devfs is mounted on top of it), vgchange skips the
