Please give more details, but note that
people often misunderstand how this option works.
I.e. `du -x DIR' reports only on files under DIR with the same
device number (file system) as the command line argument, DIR.

However, if you run `cd /; du -x *', it does the same thing for
each argument -- much as if you were to run `du -x S' for each name
matching `*' -- even if they're all on different file systems.
