These issues and limitations of casper stop users from having a
persistent, updated clone of an ubuntu CD image using usb-creator.

I have seen many complains that updating using a key (built with
usb-creator) causes the key to be non-usable afterwards. I use
usb-creator for the purpose of installing to computers via USB, not
running a full installation with the ability to update the kernel.
usb-creator works, it does what it's supposed to and fits the purpose of
making a USB installer. However, since the image contains update-manager
which will inevitably check for updates, we are setting up the user to
mess up their system because of live environment limitations. How can we
correct this or at least minimize the chances of someone updating? How
can we make it clear that there is a difference between a USB CD clone
and a USB installation?

Personally, I do not face any of these issues since I use ubiquity to do
a full installations to a USB drives. I believe that this use case
should also be tested and supported.
