The problem I've found with that approach is that a syntax error in
the cfengine.conf file can prevent further copies from working.  Also,
you need cfd to run on the central server.

I use this instead (a slightly modified cfdaily from the distribution
examples).  You need to set up a rsync server on the mainhost
machine.  The actual rsync is very quick and reliable, not to mention
that it has a lot of useful options and allow/deny host rules.

The place where main-cfengine files live on mainhost should not be the
same as the CFINPUTS directory, so you can execute the same cfdaily
script on any machine.  Otherwise you need to do if-thens, and so on.
