Here goes. I'm working on BeleniX liveUSB session saving. This would allow users to save back changes that they make to their environment back to the USB, thus making it available the next time the USB boots. Now there are stuff that belenix asks for a PC: Keyboard choice, decktop env (KDE/xfce) and the desktop resolution, network settings, etc. I plan on saving these settings too, so they dont need to be asked everytime. the scrips will identify that old setting of that PC and boot accordingly. This could be interestign for livemedia project as well (think encrypted liveUSB with xlofi) To do this I need a method to identify the particular PC. this the need for a pcid or signature for a particular machine. All the scripts to do tis are ready now excluding the 'signature.sh' ((which currently just holds 'echo 4012323') Alan pointed out an issue, however I dont think it should be of much worry as the o/p of scanpci will be the same for a particular build of ON. I hope I've conveyed that well enough.
