I see this so simple entry at /etc/fstab:
aufs / aufs rw 0 0
And the mount:
aufs on / type aufs
I see the readonly tree is here:
/lib/live/mount/rootfs/filesystem.squashfs/
I've read at this page:
http://docs.master.dockerproject.org/engine/userguide/storagedriver/aufs-driver/
that deleting files from readonly layer makes Aufs to create a
"whiteout file" with name begun with ".wh."; but I've tried to
remove /initrd.img.old and then I haven't found any file with this
command:
sudo find / | grep -ie '/\.wh'
Docker documentation may have more details about all this.

I have written some scripts for Knoppix to realize a
"drive friendly" persistence: saving changes to HDD only at
shutdown (or anytime you want). While in the traditional way
changes to live system are written immediately to
persistence data storage file.
Now I want to do this for Debian Live, too. But there is a
problem. In Knoppix there is a /ramdisk directory where all
changes to live system can be found. I can easily synchronize
this directory with a directory on HDD (and vice verse). But
in Debian Live I cannot see any directory containing the
changes to live system. I think due to the fact that Knoppix
uses UNIONFS.
Does exist such a directory in Debian Live? If not, how can
be saved the changes to live system into a directory?
