Will probably want to include "eno" in your grep statement. Not all Etherned devices come up as "ens". Not sure if there are any other varations.

Thanks! Yes, I knew ifconfig was deprecated, hence why I knew this was a hack and was asking. Is that postscript something you wrote yourself?

For starters Centos 7 doesn't install ifconfig by default, though I've solved that with my kickstart, but more to the point the postscript explicitly looks for "Ethernet" in the ifconfig line to grab the interface name which doesn't work on systemd OSes like Centos 7. And of course there's the change from "eth" interface names to "ens" and a variety of other names. I changed the line that looked like this in the postscript: interfaces=$(ifconfig -a | grep "Ethernet" | awk '{print $1}') To this: interfaces=$(ifconfig -a | egrep "Ethernet|ens" | awk '{print $1}') And while that does parse out the ens interface names now they come with a colon tacked on to the end of them in the ifconfig output like this: ens160: ens192: I can parse that out with a regex substitution to remove the colon, but before I hack the default script up too much has there been an alternative ifcfg-eth postscript released for systems like this? I'm using this script to change the /etc/sysconfig/network-scripts/ifcfg-* files from using DHCP to the static addresses defined through xCAT, which works fine on my Centos 6 OSes.
