[Fedora-livecd-list] Writing to /mnt/live/ on shutdown

[Mads Kiilerich]

Hi

I have a custom built Live image that is based on fedora-live-desktop. 
It is written to USB with livecd-iso-to-disk .

I would like to automatically stop some service and save a bit of data 
to the USB device when shutting down.

There are many ways of doing it that works just fine and can write to 
/mnt/live/ during normal operation. But for some (various?) reasons none 
of them works when shutting down. Working on a live image and during 
shutdown makes it a bit tricky to debug.

Have you been able to do something like that?

Or how would you do it and which obstacles do you expect to meet?
