You don't want to find out.  Consider the EFI partition on an IA64
version of OpenVMS, and what would happen if DFO (or some other defrag
tool) tried to move it.

The short answer is not to run DFO on a boot disk.  This way the
system doesn't need to be shut down in order to do the /NOMOVE stuff,
and you don't risk screwing up system files.

If boot disk fragmentation is an issue then move all the log files and
other update/write intensive files off the boot disk to some other
spindle.  Then you end up with two good things: a read-only (or nearly
read-only) boot disk, and a safe defrag environment.
