I recommend using the "network" service instead of "NetworkManager" if you are using bridge devices (because NetworkManager cannot manage them).

Thank you very much for your thoughtful reply. I think that NetworkManager is still useful for wireless networking that the iMac has built in, and disabling NetworkManager may not necessarily solve the problem of calling dhclient after waking up. I suspect that it is possible to retain the benefits of NetworkManager for other transient networks while solving the immediate problem of calling dhclient on waking up.
I have as a consequence already had both enabled: $ for i in NetworkManager network;do chkconfig --list $i;done NetworkManager 0:off 1:off 2:on 3:on 4:on 5:on 6:off network 0:off 1:off 2:on 3:on 4:on 5:on 6:off
