[debian] moving installation from sd card to flash

[arne anka]

a few questions:
- to move an installation from sd card to flash: is it sensible/sufficient  
to delete everything from flash and copy from sd card?
creating a jffs image and flash it to the fr seems rather long-winded.
- to those havin debian in flash: what do you have in flash what on sd? my  
debian uses about 600mb which is clearly too much for the 256mb flash --  
but what should (eg for better performance) reside in flash?
- what about the suspend/resume corruption? running from sd entirely never  
caused any problems, but that might change when running from flash -- and  
since the apm suspend/resume scripts are not executed, the workarounds  
form 200X.Y are pretty useless.
