Hi, I was discussing the common practice of disk eradication used by many firms for security. I was thinking this may be a useful feature of ZFS to have an option to eradicate data as its removed, meaning after the last reference/snapshot is done and a block is freed, then write the eradication patterns back to the removed blocks. By any chance, has this been discussed or considered before?
