Daily builds are no longer livecd images

Thank you.

I added the "--overlay-size-mb <size>" to the script invocation, so 
it now is:  'livecd-iso-to-disk.sh --format --overlay-size-mb 600 
--xo --xo-no-home /media/disk/20090519.iso /dev/sdf1'.  That caused 
additional file '/LiveOS/overlay-LIVE-AA00-0383' to be allocated on 
the USB stick when its content was being built.

[But note that when I run 'livecd-iso-to-disk' on my Ubuntu 9.04 
(Jaunty) system (with latest kernel released by Ubuntu), I'm still 
getting the error:  "running kernel cannot mount the squashfs from 
the ISO file to extract it.  The compressed squashfs will be copied 
to the USB stick."]

When I booted the XO using that USB stick;  made system changes; 
shutdown;  powered off;  rebooted with the USB stick -- the changes 
I had made had "evaporated".

What can I do to make my changes "persistent" when booting an XO 
from an USB stick ?  [It is not realistic for me to acquire a Fedora 
desktop system to run 'livecd-iso-to-disk'.]

Thanks,  mikus



p.s.  On the USB stick, in the file '/boot/olpc.fth' (generated
       by 'livecd-iso-to-disk'), the line that sets up the boot
       parameters specifies: 'reset_overlay'.

       What does 'reset_overlay' as a parameter do ?  Should it be
       there ?
