Comment 5 for bug 144595

I used the following variation to fix it:

PATH=/usr/sbin:/usr/bin:/sbin:/bin # only had /sbin and /bin in maintenance mode
mount /dev/sda1 /boot # I have a boot partition
# not sure what is needed here, but this is what I did:
apt-get install dmraid
dmsetup mknodes
update-initramfs -u -k all
