RH 7.2 switched over to using ip utilities for networking. That was a good
move. Unfortunately most of the networking init scripts still assume
ifconfig - and DHCP from ISC essentially uses a hacked up BSD script. BSD
- as befits its age - only uses ifconfig and thus the script really does
not work.

I have a script hacked up to work with PakSecured as I only use the ip
utilities but I would instead strongly suggest you just use pump on RH.
COX is using CIDR subnetting for the lease address space and that
complicates the mask provisioning. Pump is fine for single port use in
these circumstances.
