Bootable USB

Jim,

I'm not familiar with the RedHat/CentOS/SuSE world; I've mostly stuck to
Debian derivatives, so...

Doesn't 9.04 come with an option to create a bootable USB device? (I
don't run 9.04 much and my only 9.04 box is about to be replaced with
gNewSense 2.2)

My FSF membership card is bootable to gNewSense 2.1, although I didn't
install it so maybe it was hard :)

I believe the Ubuntu community has been enjoying the fruit of these
labors for about a month.

As for me, I don't have many boxes that can boot off USB. So Live CDs
are not going away but it's great to have more options. (Plus you don't
have to keep making plastic discs that aren't so handy when the next
release hits, RW media notwithstanding.)
