I don't know. I have not tried it yet.
How would I verify something like that?
Gdisk reports my root filesystem is 240197632 1K blocks long.
$ factor 240197632
240197632: 2 2 2 2 2 2 2 2 2 2 2 2 2 109 269
So 2^13, or 8KB is the largest block size where input and output would
match.
I don't quite follow the logic.
Can you please elaborate ?
