I installed openSUSE 12.1 on RAID1 /dev/md1 with a separate /boot on
/dev/sda1. /home is on a pre-existing RAID1 /dev/md0. However when I
start the new installation, the startup fails; unable to mount
/dev/md0 on /mnt/home. I get thrown into emergency mode and onscreen
I see
Mounting root /dev/md1
mount -o rw,acl,user_xattr -t ext4 /dev/md1 /root
system-fsck[693]: /dev/md0 clean
Welcome to emergency mode

The complete dmesg output is a bit too long for a posting - its
available at http://rogerprice.org/dmesg The last 38 lines contain all
the references to md0:

If I now type “telinit 5” the startup continues until I see the login screen.
Why is the startup unable to perform the “mount -a” which works
correctly when entered manually? Any suggestion for fixing this would
be much appreciated.
