Interesting, so what is the difference in terms? Wouldn't the privacy concerns be from residual files?


Yes, but... residual *files* just DO NOT EXIST ANYMORE after a mkfs.

What *can* exist, maybe, are residual *fragments* (blocks or sectors, since the original inodes and index structures were wiped away by the mkfs) which a clever forensic technician could maybe piece back together,

So, zeroing out the partition is a reasonable operation for a /home or /data partition (where you'd keep sensitive data), but not for something as mundane as an OS-only / partition.

BTW, I like having a separate /data (or whatever you all it) partition, and recommend that you also having a separate /home.
