No, though you are close:

The way rdist copies files about might seem rather strange at first,
but if you think about it you will see why it is done that way.
Rdist creates little temporary working files for everything it will
update before it actually goes about updating them.  If you are
running another rdist at the same time, in particular with the `-R'
flag, it will tend to spot these `anomalous' files and remove them.
The first rdist complains as soon as it tries to find the file
again, and your rdist command is told to exit(1).

It is best to run exactly one rdist at a time, and only from one
`central' machine, so that multiple rdists will not interfere with
each other.  If you are sneaky, you can use `special's to sequence
rdist runs, if you must have more than one `master'.
