Bug Description

I have tried installing Kubuntu Breezy preview (daily build 20050902).
Installer did not detect my other system (Suse 9.3) which is on RAID partition and did not add menu entry in
Grub for it.

I have installed Kubuntu on /dev/hda8, here is fstab from Suse system (Suse is booted from /boot, which is
also on RAID partition):
/dev/md3 / reiserfs acl,user_xattr 1 1
/dev/md0 /boot ext3 acl,user_xattr 1 2
/dev/md1 /boot2 ext3 acl,user_xattr 1 2
/dev/md2 /boot3 ext3 acl,user_xattr 1 2
/dev/md5 /home reiserfs acl,user_xattr 1 2
/dev/hda8 /root2 reiserfs acl,user_xattr 1 2
/dev/hdd8 /root3 reiserfs acl,user_xattr 1 2
/dev/md4 swap swap pri=42 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
sysfs /sys sysfs noauto 0 0
/dev/dvdrecorder /media/dvdrecorder subfs
noauto,fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0

os-prober was changed to exclude software RAID partitions altogether as a
somewhat quick hack around http://bugs.debian.org/273960; it needs to be fixed
properly at some point, while still making sure not to list each component drive
as containing a bootable OS.

This appears related to Bug #1217933 and I have a basic patch that enables it for mdadm RAID.
