mdadm: Failed to assemble all arrays

[David Andel]

Funny enough, now after having sterted with Knoppix again I see mdadm.conf
generated by Knoppix just now has changed:

root at Microknoppix:~# cat /etc/mdadm/mdadm.conf 
# mdadm.conf
#
# Please refer to mdadm.conf(5) for information about this file.
#

# by default, scan all partitions (/proc/partitions) for MD superblocks.
# alternatively, specify devices to scan, using wildcards if desired.
DEVICE partitions

# auto-create devices with Debian standard permissions
CREATE owner=root group=disk mode=0660 auto=yes

# automatically tag new arrays as belonging to the local system
HOMEHOST <system>

# instruct the monitoring daemon where to send mail alerts
MAILADDR root

# definitions of existing MD arrays

Of course this one is not used by my native system, but it shows that the
devices 0, 1, and 4 have been built by the new mdadm version running in the
chroot.
And they are called /dev/md/1 instead of /dev/md1 now.
Maybe I should build them this way after break=mountroot...??
