That *shouldn't* be an issue, because installadm will only modify configuration 
entries for devices you want it to work with (i.e. explicit mac addrs passed 
via create-client / delete-client). If there are other entanglements, please 
let me know.

Right, you can basically have redundant entries... but that's kind of bogus if 
for no other reason than tracking/bookkeeping purposes. Plus, as those get more 
complex, certain elements will cause an entire stanza to take priority over 
other ones, and things can get very gross.

Thanks for your view, much appreciated.
