"if" and "of" with the exception that the communicate with a rump kernel instead of the host kernel. For example, to write stdout to /tmp/file.txt in a rump kernel namespace: dd rof=/tmp/file.txt copy /file1 to /file2 inside a rump kernel: dd rif=/file1 rof=/file2 copy a snippet from /dev/rmd0d on the rump kernel to the host fs: dd rif=/dev/rmd0d of=save seek=1000 count=3 Eat that, usermode OS. (I'll document the operands one I have some manpage to refer to for rump client use).
