I'm not sure if this expected behavior, but the following command (at least) will wipe a mounted filesystem, such as the filesystem containing the operating system nwipe is running off of:
nwipe --nogui --nowait --autonuke --method=zero --verify=off /dev/sda1
(I expected it would quit with an error if a mounted filesystem was specified.)
