Kam,
I wrote a script to check the status of the overlay (attached). I'll
see if I can get it included for future use.
Has anyone else had the overlay become
corrupted when it gets full? I had
this problem too... df -h said I had a bunch of free space so I installed
lots of extra packages but then I got a error message saying "read only
filesystem" I after that I couldn't run "rm" or even "ls".
When I rebooted
from the USB key again, it complained about logical buffer errors and I had
to regenerate the overlay to fix it.

Hi Stewart, I am hoping to understand the issue enough to build a suitable application for
montoring the overall overlay health including free space. Something simple such as green,
yellow, red light in a task bar applet.
