I assume that all of the disks are to be shredded. Shredding non-system
disks wouldn't be difficult enough to ask about. If you shred a mounted
filesystem, the kernel will probably panic if it tries to read from the
filesystem after shred starts overwriting data.

You wouldn't be able to do that once shred had run.
