My bad, apologies, dm-verity is used to verify the boot path and deals with read-only fs. With FEC it would also be able to recover from some limited data corruption. I meant to write *dm-integrity*! Thanks for correcting me. Either way, if the data being written is corrupted due to faulty RAM, the result will be corrupted too.
