I've just installed unetbootin on 8.04 - seems to work fine.

Assuming it's been available for sometime i do wonder why ubuntu
haven't incorporated such until ver 8.10. I imagine the 8.10 app is
similar to unetbootin.

Doesn't seem to make sense to me. I've been using ubuntu since may 07
ver 6.10 i started with burning CDs for each version. If one can't
bootup on a usb - one has only got to use an older version live CD to
install from the usb. Bearing in mind that a new release could well
need to have more space in future than a CD 700 mb (or there abouts)
why has it taken so long to get round to it.
