JFYI: If it's just configuration files and stuff inside $HOME you
could use grml-saveconfig too, but your approach looks nice. :)

If you are using grml in live-mode (which you seem to do :)) you can
use for example the configuration framework with grml.sh.  Just
place a grml.sh script on your device and check out the
possibilities you have in the docs:

If you have any further questions don't hesitate to ask. :)

JFYI: http://grml.org/faq/#init -> you mean /etc/runlevel.conf - but
notice that adjusting runlevel.conf usually does not work as
intented unless you are re-reading the file using 'telinit q'. ;)
