[Unionfs] UnionFS as root filesystem

[Tomas M]

No that is not correct, you CAN use unionfs for making union of two 
devices - but mounted.

This way:

mount /dev/hda1 /mnt/hda1
mount /dev/hda2 /mnt/hda2
mount -o dirs=/mnt/hda1=rw:/mnt/hda2=ro unionfs /mnt/union
chroot /mnt/union # or whatever you need to use, eg. cd /mnt/union; exec 
sbin/init <dev/console >dev/console
