Let's say I am on Arch Linux (any non Ubuntu Linux), and I don't have
access to the internet. All I have is an Ubuntu 10.04 iso image on my
machine's hard disk which I had downloaded earlier (when it was
connected to internet). Also, my machine does not have a CD/DVD drive.

In this situation, I want to convert that iso to an usb image and put
that image on to my pendrive, and install Ubuntu 10.04 on this machine
(without going through the old tedious process of mounting the iso,
editing the syslinux config file, etc).

In recent distros like openSUSE 11.2, they create the iso image such
that just 'dd'ng the iso onto a pendrive makes it bootable. Is that
true in Ubuntu 10.04's case too?

(please see: http://en.opensuse.org/Live_USB_stick, and also

I hope I could explain properly now.
