1. Unetbootin has been in the Ubuntu repos for many years :-)


2. But cloning the iso to a USB pendrive is a more reliable alternative,
particularly during the development cycle, and I made mkusb to 'wrap
security around dd' for that purpose. mkusb is not in the repos [yet],
but there are PPAs

While

sudo add-apt-repository ppa:mkusb/ppa
sudo apt-get update
sudo apt-get install mkusb

will install the stable version of mkusb

the unstable PPA

sudo add-apt-repository ppa:mkusb/unstable
sudo apt-get update
sudo apt-get install mkusb

# if you want mkusb-nox
sudo apt-get install mkusb-nox

# or if you want both mkusb and mkusb-nox
sudo apt-get install mkusb mkusb-nox

will install the bleeding edge version of mkusb and/or mkusb-nox
(testing new features and bug-fixes)


3. Unetbootin and usb-creator can be used, when you want persistence in
the same drive. Otherwise persistence works with an ext[234] partition
with the label casper-rw, and that partition can be 'anywhere', in
another pendrive or in an internal drive (which makes it faster).
Persistence with an ext partition 'anywhere' works when booting from a
DVD as well as from a cloned iso file (from a pendrive made by mkusb).
Just add the boot option 'persistent' when you want persistence. Then
the live system will search for a casper-rw file or casper-rw partition.
