I guess the sequence will be bottom to top. Like: 
    mount / -> mount dazukoFS on / -> mount /home -> mount dazukoFS on
/home 

This can work even for /proc and /sys etc. The only issue would be with
removable media
for which there are no fstab entries. Most of the newer distributions
are using hotplug to
mount USB flash drives and other external storage media. One way would
be to either 
monitor /etc/mtab || /proc/mounts to know of a mount event and then
mount dazukoFS 
on it or to wrap the mount command itself. Both look messy to me. Any
solutions ?
