[SoaS] LiveUSB Duplication coming to SoaS

[Sebastian Dziallas]

Hi all,

I've been looking on (and discussing with Martin) ways to replicate USB 
keys directly from a running SoaS and have now a first incarnation of a 
script ready. It has been merged into GIT, but for now, you can also 
grab it from here: http://sdz.fedorapeople.org/liveusb-to-liveusb.sh

This might go away soon, though. To run the script, just execute it from 
the terminal and provide it with the location of your second USB key 
(the one you want to copy the image to). Here's an example call:

    sudo sh ./liveusb-to-liveusb.sh /dev/sdc1

So what does this script do? It basically runs livecd-iso-to-disk as 
described in RHBZ #448030 and copies in the end some missing stuff over. 
Finally, it adjusts the kernel arguments to make sure you're able to boot.

Limitations include currently no way to set up an overlay without 
pondering with the script itself. Please test it and let me know how it 
goes!
