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?
