Ok, thank you - I will try to get your firmware up and running it
without backup and look what I can do with a script (and will not
blame anybody if my data gets lost :-) Will need to learn more about
NFS before I do that, I guess.

OT: Re-Mastering Ubuntu is basically nothing more than switching to a
clean chroot Ubuntu environment, doing your changes (apt-get install
xxx etc., change /etc/skel etc. and then re-pack it into .ISO.

If you use Reconstructor then this is IMHO simpler than tweaking the Icy :-)
http://reconstructor.aperantis.com/  --> makes a lot of fun, the
possibilities are unlimited, together with VMware and loooooots of HD
space, you can create the craziest Ubuntu derivatives.

not really if don't use twonky you can use the tinky hack
to access the nas and then write a little script (not a big thing if
you remaster Ubuntu DVD)

usualy the backup is not needed but I don't want to get blamed
if you lose your data! So its always better to expetc that the data
will be lost :-)
