I apologize I was not careful in reading your original post :(
Just a wild guess -- there is also a dhcpv6-client package;
though it has much lesser probability to be used by you
though you say NETWORKING_IPV6=yes I am not sure if you actually do
any IPv6 there, but could be a possibility. dhcpv6-client does not
have a dependency on dhclient, so it would not have been removed
along with dhclient.

Indeed. Especially if built from the same kickstart and the hardware
appears to be same.

Please let us know when you figure it out; I am curious if it is
hardware.

You should also compare if the systems really have the same
packages installed by diffing the 'yum list installed'
output from all the machines, or at least between one of the
7 and one of the 2 that don't show the behaviour.

Also, are they 64-bit or 32-bit?
