NOTE: THIS MAY NOT WORK FOR YOU, LIVE CD/USB CAN MODIFY YOUR COMPUTER'S HARDDRIVE RENDERING IT UNBOOTABLE.
# kubuntu 8.04 liveusb persistent
# I've always been annoyed, that it couldn't be removed or hidden. Not that I'd click on it unintentionally.
# I created a start-up script for it in kdesudo kate (follows)
#!/bin/sh
sudo mv -f /home/ubuntu/Desktop/ubiquity-kdeui.desktop /home/ubuntu/Desktop/.ubiquity-kdeui.desktop
# I saved the file to /etc/init.d/hide-Ubiquity-kdeui-from-Desktop
# Then in konsole I did:
cd /etc/init.d
sudo chmod +x hide-Ubiquity-kdeui-from-Desktop
sudo update-rc.d hide-Ubiquity-kdeui-from-Desktop defaults
sudo sync # I do the sudo sync before shutting down or rebooting my liveusb kubuntu8 persistent
# Then I did a shutdown. (my computer doesn't see the usb when it stays plugged in during a reboot)
# (It's OK if I want to do reboot to my computer's installed OS's.) I've also found on my liveusb w/ persistence
# that the casper-rw sometimes gets uncleanly unmounted from persistent run so I'll do a non-persistent boot
# between each persistent session and run e2fsck -yf /dev/sdX#
# (my casper-rw is /dev/sdb3, if you do it yours may differ)
# Anyway, end result for me is when booting liveusb kubuntu 8.04 persistent, the file for Install is still there
