 Replying to [comment:2 marco]:

 > In general though I don't think there is way to be completely safe
 against a power failure. I think OHM or Sugar should shutdown the system
 when the batter is about to dry out.

 Databases have done this for years. Being safe means atomic transactions.
 Some filesystem operations are supposed to be atomic; jffs2 is responsible
 for taking that all the way to the storage.

 Bonus: if you make things safe for power loss, then you can eliminate a
 bunch of code (including any bugs) by ripping out the shutdown code.
