Hello,
 
There are some issues in Fedora 9 when using a bootable USB stick with a persistent overlay (created using livecd-iso-to-disk).  Filling up the overlay renders the USB stick non-bootable.  Whatever the reason for this, has the issue been resolved in Fedora 10?
 
Also, once desired changes have been made to files on the USB, using the persistent overlay, is there a way (in Fedora 9 or 10) to disable further writes to the overlay, basically "freezing" it so that no further permanent changes can be made?
 
Thanks in advance for any input.
Todd
