It uses shred, in the hope it will somedays learn how to shred stuff on
FLASH based devices securely too, once that has become possible.

BTW: This is a good example where technology failed to keep the needs of users in mind.

It should be relatively easy to make that possible: Using secure trim which erases blocks instead of just marking them as free, it should be possible without much effort for file systems to implement a secure unlink. An obvious name would be sunlink(2). Or does such already exist? I've seen secure trim already exists for some devices, but not sunlink().
