Not a question but a comment

This a great great tool.

I've made quite a few Live usb devices before but this saves me so much time. I need multiple copies and so I created a master image on USB and then used DD to copy it to each new device, however if you don't buy your usb devices at the same time you might get a different batch from the factory (even though it's the same model number) resulting in devices slightly smaller which screws your partitions.

I use reconstructor (http://reconstructor.aperantis.com) to customize the environment adding a lot more packages including liveusb and custom scripts.

I then remove the ubiquity installer icon on the desktop by chrooting into the build area and deleting /usr/share/applications/ubiquity-gtkui.desktop from the filesystem.

Create a DVD iso and boot from it, then use liveusb to install on various devices, I have a Levovo T61 with 2GB of RAM and I can do a stick in five minutes, which is great.

Thanks very much for developing this great tool.
