I am developing an application on a Linux embedded board (runs Debian) e.g. Raspberry Pi, Beagle Board/Bone, or olimex. The boards works on an environment that the electricity is cut unexpectedly (it is far complicated to place PSU, etc.) and it would happen every day couple times. I wonder if the unexpected power cuts would cause crash/problem on the Linux Operation System? If it is something that I should worry, what would you suggest to prevent the damages on OS against the unexpected power cuts?

PS. The application needs to writes some data to the storage medium (SD card), I think it would not be suitable to mount it as read-only.
