--- Comment #6 from Eric Sandeen ---
As long as you don't truncate the file first, overwriting an existing ext4 file
will indeed overwrite the existing blocks allocated to that file. Ext4 is not
a copy on write filesystem.
FWIW, recent kernels and recent util-linux also have "fstrim --secure" to issue
a secure discard post-deletion.
