Is it possible to use etfsctl to non-destructively (i.e. without erasing the flash partition first) update an existing 
flash partition?  Maybe I'm misunderstanding what mketfs does in building the set of "transactions" represented by the 
commands in the build file, but it would be very useful to use mketfs/etfsctl to update an existing flash partition 
without completely blowing it away by erasing it first.

Thanks,
