hey guys
There's still the simplistic hack way I mentioned earlier
step 1)
download and install NetBootCD to your usb
http://netbootcd.tuxfamily.org/
step 2) go here and prepare a new /etc/apt/sources.list, for your country and squeeze or sid
http://debgen.simplylinux.ch/
step 3) bootup netbootcd on usb and tell it to install squeeze or sid, etc
it will probably install Lenny; which is why you need the debian sources list generator above
step4 ) after NetbootCD is finished installing; reboot and from another system or livecd
copy the new sources.list for squeeze/sid to your /etc/apt and overwrite old one
also making sure you get the gpg keys, etc
step 5) do apt-get update after replacing the sources.list
step 6) do aptitude -f safe-upgrade
after it finishes reboot
step 7) complete it by upgrading anything else with another aptitude safe-upgrade
thats how I initially made nfluxos squeeze.
The other option would be to install nfluxos squeeze and trim it down or up, whatever
