I used the <a href="http://www.pendrivelinux.com/2008/05/08/usb-ubuntu-804-persistent-install-via-the-live-cd/">pendrivelinux instructions</a> and it worked. <br>Sure, I formatted with fdisk, setup my partitions etc. and it worked.<br>
Let me repeat it again: before hardy came out, I was using persistent mode with my usb stick and everything was fine.<br>The problem here is how to get the new initrd into the iso and keep the iso bootable.<br><br><br>
