You need to set some flag to indicate that the command has been run, and
test for it.  For example, on my Red Hat boxes, I need to run chkconfig only
if the service hasn't already been enabled (or disabled, depending) on some
systems.  So I do some funky stuff in shellcommands to do the test and set
a class, and then if the class is defined run chkconfig to turn on or off
the service.
