Hello yooy;
thanks for trying it...
Now, as for Unetbootin, it doesn't really install it to usb as it should...
Use Ubuntu's usb-creator and I also included usb-creator.exe on the iso
however, you can install it to usb, with persistency very easily
1) use the app "isomaster" to extract iso to a folder somewhere on hdd
2) rename isolinux folder to syslinux
rename isolinux.cfg to syslinux.cfg
3) in ubuntu/debian, open a terminal and become root with "sudo su"
4) you must do this from installed system or cd, as usb will be read-only if booting from usb.
after becoming root, mount the usb with the ubuntu cd extracted to it(already is yes?)
5) cd into usb and execute these commands
assuming usb is /dev/sdb1, mounted as either /media/usb0 or /media/disk
Code:
cd /media/disk
or
cd /media/usb0
dd if=/dev/zero of=casper-rw bs=1M count=128
the above command will make a persistent file of 128MB in size
so, change count= to whatever size you want, 2GB max I think...
6) format the casper-rw file
Code:
mkfs.ext3 casper-rw
see here for more info, as you can also make a partition on usb labeled "casper-rw", of whatever size, and it must be ext3

now, ubuntu you can't really upgrade the kernel, etc in persistent mode...
you must remaster the cd, and you can as it has remastersys

it must be installed to hdd to remaster.
anyway, theres also the official Maverick Meerkat daily build here
http://cdimage.ubuntu.com/daily-live/current/
and you can keep that iso up-to-date without having to download new iso's using "zsync"

very cool
EDIT
Note that my iso can also boot from iso off hdd, usb
if using grub2,
