I dont know if you resolved your issue. Im writing this because I spent several hours searching on google about this without luck.

After studying the structure of the overlay file I found how it works. Im currently working in a project that requires to install so many things on the live usb, and it was a pain in the neck to install one by one. What you need to do is the following, very basic steps and very easy to do. No complicated dd commands or iso creation.

Do the following(UNDER WINDOWS):

1. once you have the final usb installation, you need to get the System Volume ID. to do that simply plug the usb and goto system command (start -> run -> cmd.exe)

2. type vol DRIVELETTER: (for example if your drive is F: do vol f:) once you do that you will get something like:

Serial Volume is: 0AD7-0FF0

3. Write down that number. Now, you need to download an application called VolumeID from microsoft. you can get it on http://technet.microsoft.com/en-us/sysinternals/bb897436.aspx. download it and unzip it.

4. take the new usb and format it. once formatted open a cmd.exe window and run the command volumeid(from your previous unzip).

volumeid DRIVELETTER: SERIALVOLUME i.e. volumeid f: 0AD7-0FF0

5. once you do that you are "cloning" the serial volume from your original usb into the new one. Overlay files depends on this.

6. now open the liveusbcreator and create a live usb as you normal do. Once its finish just overwrite the overlay file (located in LiveOS folder). Make sure to label your usb as same as the original one. Once you overwrite the overlay file the usb is cloned.

I did this and works. Any further questions send me an email to fer507 at gmail dot com

After a recent hard drive crash on my laptop, I've been trying to limp along by installing f11 on a 8GB USB stick. After an installation from a live USB stick to another USB stick, I drove to a local hotspot to update and yum install some stuff that wasn't on the live USB. It took forever to update, not even counting the download time. I'm sure there is a reason, but I was surprised that the original installation took about 7 minutes and it took several hours to update that installation AFTER downloading all of the updated rpms.

Anyhoo, now that I've spent most of a day getting the USB stick updated and configured, I want to clone it to another USB stick. I tried a few naive things like copying directories to the backup stick, but ran into boot errors (I think due to different uuids on the backup sticks partitions). What is the right way to clone a fedora installation on a USB stick to a second stick that isn't exactly the same size (they are both 8G, but different models so have slightly different sizes).

Thanks,
